anyone know how they do this

the alternative is putting your hands in your pants instead of your stomach...

I don't know how to describe it so I made an awesome x-ray picture description

I am going to do this in the street not giving as fuck

one arm in one sleeve and the other arm under the jacket doing the popping motion. the other sleeve is empty and they just hold it but they move too fast for it to be clearly visible.

even though it's a comic and doesn't mean people actually did it

but I'm sure someonme out there has done something similar

That is my fetish.

better?

Because 9gag sucks.
