Johnny says to his Friend Sidney "Hey man , i havent had my share of pink sandwich in months ". Sidney replies "Try My vag-in-a-can" . "Whats a vag-in-a-can" Demands Johnny. "Its a can shaped vagina that you can penetrate !! , all u have to do is give it a wipe down and put it back in your draw ;)"

As found in Yahoo personals: Don't even think about contacting me if you have a purple vagina candle! WTF man, comeon....what the hell is that buzzing? Oh it's just the neighbor on the roof with her vagina candle. God I wish I could get some sleep, tell her to knock it off!!
