I want one. Intended for audiences over the age of 18! http://www.spikedhumor.com/articles/4542/Pussy_Bong.html
I think the bottom of the champer is open ended, using the vag as an integral part of the bong. Without the vag, it's just an open tube with a bowl.
I like that movie! Everyones high, the one dude in the background is laughing uncontrollibly, the one dude is surprised it worked, and the hot chick and her pussy! Nice find! So peace out!
