I was over at my girlfriends house, and she asked if I wanted some tang to drink. I said sure. She went into the kitchen.
A minute later, I heard "What flavor Tang do you like?"
Being funny, I said "poon" (poontang = pussy).
Her mother stepped out of the kitchen and said "Excuse me?"
It was her Mom! They sound so much alike, and I didn't know she was in the house!
My face turned red, but she just laughed.
