I feel like I always reference this... but the 80's. (Well, 80's America)

Get 80's clothes, all that stuff. Somehow become an extra in a movie, take selfies and have people ask me "What the heck are you doing? Lameo..."

(*cough cough* steal all episodes of AATC which were rightfully mine *cough cough*)

Then come back with that photo and show it to a random kid on the street and say "Look Son, I was there..."

Then back even further and murder the guy who invented homework!!!

I will go back to yesterday's dinner~ it was delicious~!!!

I'd go back to like 70's, Or 80's
To see all the concerts that were back then!!!!

I dunno, the future could be depressing for a tonne of reasons ...

Back to the Vikings because they allowed women to become warriors.

I'd buy all of the games and systems that I missed out on!

Medieval era!

Ancient Africa. I want to know the truth of that history. I'll take a crap ton of pictures and notes while I'm there too.

I would go back in time and kill the man who invented/discovered wheel, come back and enjoy watching engined mechs dragging their asses around... or maybe we'll have some cool sci-fi mechs. You never know.
