Here's an old one:
Face a wall standing behind a chair and lean over resting your head against the wall and try to lift the chair and stand upright. If you're male, you won't be able to do it but get your wife or GF, any female to try it. She'll do it with no effort.

EDIT: Forgot to mention, you must keep both feet flat on the floor. No stepping back.
So, you face a wall, but you're behind a chair.
 How do you rest your head on the wall, then turn around and lift this chair?  Or is the chair behind you what's facing the wall?  Or is the wall standing behind the chair???  I don't get this; I think only a female could do it.
