OK, so this big ol' biker chick wants to get the words "Biker Babe" tattooed on her butt, one word on each cheek as a surprise for her biker boyfriend's birthday.
She asks the tattoo artist how much it'll cost and he tells her "At $100 a letter, that's nine letters, $900."
She thinks that's a bit steep, and asks "Ya got anything cheaper?"
He says, "How about a big B for 'Biker' and 'Babe' on each cheek, $200?"
She agrees, so he does it.
When she gets back to the biker boyfriend's boudoir, he's sitting there in the recliner with the remote control, a can of beer and a large spliff, celebrating his birthday.
She says "I've got a surprise for you honey." and she drops her jeans and panties and bends over in front of him.
He says "Who the hell is BOB?"
