Bloke walks into a shop - he says:
"I'd like a Fender Stratocaster please". The shopkeeper says:
"Are you sure Sir?" The bloke says " Yes, absolutely sure, a Fender Stratocaster. That is most definitely what I want".
Shopkeeper: "Really, a Fender Stratocaster?"
Bloke, irritated: "Yes! I want a Fender Stratocaster!"
Shopkeeper: " You're a drummer, aren't you Sir?"
Bloke, incredulous: " Well, yes, I am a drummer. How did you know?"
Shopkeeper: " Because this is a butcher's, Sir"
