Probably one of the meanest and funniest prank I have seen in years. Just peel the logo of a hair removal product like Nair and place it in the shower.

Angry grandpa is a on going web series that is guaranteed to make you  laugh.

I wish my grandpa was as funny as this one. No matter how angry he gets it's just too funny to watch! Plus I love his vast vocabulary! This grandpa is awesome!
