"You should be more nice to me on my birth day!"

"It is!?!?!"

"Yes!"

"Well how about you give me one and laugh and well, not divorce me."

San Francisco Treat

Similar to the Houdini. When doing your girlfriend doggie-style, you switch out with your buddy. Now, instead of heading outside to wave to your gf, you turn around and stick it in your buddy's ass. Since everyone in SF is either openly or a closet homo, this is a treat for everyone!
