Is it possible to jump over the flag-pole in Super Mario Bros?

Yes, with a little practice you can easily jump over the flag pole on level 3-3:

But wait... there's more!

Contrary to popular belief, it can also be done on level 1-1 as Mike describes in this video:

Yes, but there's really only one level it's possible on, World 3-3:

Game Trailers provides a great video about the Mario Flag Pole jumping myth in an episode of Pop-Fiction.

But it can also be done with the Game Genie or other "hacks".

Yes it was possible but useless, only in wolrd 3-3 when you can use an elevator bar to make an higher jump. But then it triggers a bug and Mario dies :(
