A boy and girl were making out in a field. A UFO landed and two aliens came out. They approached the young couple and they all decided that they would pair off and have sex, the alien boy earthling girl, and the alien girl and the earthling boy.
The earthing girl said to the alien boy while they were having sex, "I don't want to be rude but your thing is a little too small." The alien boy replied, "well just twist my ears." She did and his penis grew way bigger.
Afterward, the aliens bid the earthlings goodbye and the UFO flew away.
Then the girl turned to the boy and asked, "How was it?"
He answered, "It was alright, but she kept twisting the hell out of my ears."

If we change the rules to where I can more than just observe, I would do a lot of things, many for my own personal gain. Guess I am just not as nice as you guys are in hypothetical situations, or maybe just more honest.

But in keeping spirit with the OP. I would get very involved in history. I would read a book, get involved with the people involved and then go visit it and see it for myself.

Since I spent a lot of time on these boards talking about theism, I would certainly head to the time the supposed crucifixion of this jesus guy and see for myself what all these billions of people go on and on about. If anything so I could smile knowing the real story, while people try to tell me what a heavily edited book told them.

Maybe I am just too logical, but with the ability to peer back in time, I tend to run into all the ways I could use that to my benefit. Watch for myself where some lost treasure got buried, so I can go recover it in my time. Watch a very embarrassing private moment of Donald Trump when he was a kid, then bring it up to him in front of a camera with exacting detail and watch his expression. Any politician that I feel may be corrupt I would go back in time and watch the corruption for myself, so I could find evidence today to present to a news publication and let media do the legwork of impeachment. Just being able to observe the past would make me the most powerful person in the world.

If I could change the past, that puts me pretty close to godlike.

Well, let's see, body odor is one of man's biological excretions and no form of cologne nor perfume can ultimately mask it. Those smell-pretty's were developed for men to attempt to combat their olfactory offensiveness and soldiering, being the primary career of men in days of old, was the main targeted purpose of perfume and cologne.

Only the most affluent had some semblance of a bathing routine. There were no such things as deodorants. I remember Right Guard was one of the first and it didn't hit the market until sometime in my early years. People sweat, bacteria forms and emits odor. My own Pop smelled like an arm pit all the time. He tried to combat it by taking baths with Chlorine diluted in his bath water but that worked only for a little while. He was a happy camper when Right Guard was introduced. He was a bomber pilot and the nylon flight suit he wore was not exactly conducive to breathing so he was a sweaty stinky hombre when he came home.

Soldiers never bathed when in the field. All smelled like ass and arm pits. Office workers in closed buildings before the advent of air conditioning were sweaty and stinky. Electric fans came along and gave some relief from the heavy still air but the sweating and stinking continued.

Hygiene and grooming, as we know it today, are a relatively new development in man to the extent that he managed to combat successfully repulsive stinkyness only as late as the mid-late 20th century. My own globe trotting through Europe, the Pacific islands, Middle East and other lesser developed places confirmed to me they were aptly named "armpits of the world" for good reason.

It was a normal part of life, though, so people gave it no thought. Bathing ultimately became more of an American routine than in Europe. European's would say that Americans were compulsive about it until it became a western civilization way of life. Western countries also became acutely aware that nations and cultures that did not have the same hygiene were to some extent doomed to a perception of being a lesser class. Yup, hygiene and grooming became a mark of civilized men. Without it you were a smelly barbarian. American women, in an effort to combat the persistence of body odor, were the first culture to begin shaving the armpits and then other body hair as it tended to confound the body odor problem. European women followed suit but only many years later when it became associated with beauty and well after the deodorants were in good effect.

Gandhi, for all his worth as a peace-loving man, was considered a second class citizen because of his lack of grooming and hygiene. He stank, so he obviously did not consider how it impacted his surrounds and that was simply irresponsible and a bit too coarse to certain people who do care about such things when in public. It became a measure of one's persona and has taken a front row seat to it since.

Youngsters want to rebel from the whole profiling of their perception of the establishment but they won't stray from ensuring they don't stink. Instead, they will ink themselves, pierce themselves and otherwise make an effort to be anti-establishment. But, they still get grossed out by stink.

So, yea, people stank. The cowboy, businessman, professional doctor/attorney/politician, laborer, office worker, wife and mother, etc, all were smelly.

I love Louis CK's time travel scenario the best.

"A lot of people say they would go back and kill Hitler. I wouldn't. I wouldn't kill Hitler. I would rape him. I think that would be enough, enough to stop the Holocaust, to be raped by me. His general would be like, 'Hitler, you want to invade Poland?' and he'd be like, 'No, I just wanna take a shower...' but it'd all be in German, obviously."

Louis CK is pretty great.
