Reminds me of the story of the bloke who is a keen lepidopterist - or even butterfly collector. For his birthday prezzie his wife goes to a tattooist and asks for a pair of butterflies to be tattooed on her buttocks. The tattooist says, "Sorry luv. I'm not very good at butterflies. Can I do bees instead?"
She replied,"By all means my good man. Please go ahead."
Come bedtime, the wife peeled orf her undercrackins and bent forward, showing her newly decorated bumcheeks and said, "Happy Birthday darling! What do you think of that then?" To which hubby replied, "Oh very nice, I'm sure! Who's Bob?"
