Going back in time to visit the lost city of Atlantis.

Go back to the 80's.

lol! Very lame.

There's a movie - not a very good one, sadly, but an interesting one - called <i>95ers: Time Runners</i>, in which some of the protagonists have a native ability to shift back in time by a few seconds (only) and explore different strategies and outcomes until they get the one they want. Now that's a talent I could have used, over the years.

Like totally lame

I would go back to where i could go back, and then i would go back there again.

I'd go back to correct all of the failed comebacks I attempted, with something better than, "Oh yeah? Well you're a big fat doodyhead! So there!", or the classic "I'm rubber and you're glue..."

Going back in time to stop The Butterfly Effect from being made.

I'd travel back to the Middle ages on a Harley, tell them I'm a Prophet just to ... get interrogated / tortured by the inquisition and die in flames i guess... wow that's no fun...

Going back to steal presents from that kid you knew as a child who always got the cool gifts that you wanted, but that your parents never got you. And then going to the past version of your house and opening the stolen gifts as recklessly and excitedly as if you were actually your childhood self.

Hope everyone who cared to had a happy Christmas. :)

Amusingly enough, I'd go back 17 years ago and leave myself messages in every corner of my flat, about the urgence to avoid any contact with a certain female creature.... or maybe go back to her birth to make sur ger parents called her Medusa or something like that, should be ok to caution any male about looking at her...

This would be so awesome

I would go back to last week to try a different dish I was considering getting at a diner and make sure I wasn't missing out.

Not sure if this one has been said, but I'd go back to when this thread was first posted and post all the best and funniest ideas myself ;)

Shove a suppository in my past self to get rid of a condition I am currently suffering.
