The Granny Panties Re-Dub Commercial Is Hilarious [Video]
Grab any retro commercial and start giving the actors your own audio, and it should turn out fairly funny. Give a leaky underwear commercial to the people at 'Jaboody Dubs', and you'll probably pee in your own underwear.
Just a fair word of warning though, this isn't for work, kids or anyone who might actually have leaky underpants.
