One morning, two Englishmen are strolling down a London street, when they see a stray dog licking its own testicles. One of the Englishmen turns to the other and says, "Say, I wish I could do that!" His mate watches the dog for a moment, sighs longingly, and replies, "I should say so! But don't you think you ought to get to know him first?"
Reply might be - Give him a biscuit and he might let you - Jasper Carrot
