What is inappropriate behavior for an adult?

your office is full of men who compete in farting contests. you still do “wet willies” or “wedgies.” you form a wad of paper in your mouth and spit it through a straw to somebody across the room. while in the bathroom, you ball up a wad of toilet paper and make it stick to the ceiling.

what is inappropriate behavior for adults? what have you seen, heard or smelled in adult situations that are inappropriate and childish? at what age should childish behavior cease but it shows up in adult behavior?

ok, pull my finger dude…
