(it's old I know but...)
A man has finished his meal at a restaurant and he is about to enjoy his pudding...he reaches for the spoon on the table but he accidently knocks it on the floor...
Man: Waiter, can I have a clean spoon from the kitchen?
(The waiter takes a spoon from his pocket and places it on the table..)
Man: That's strange, why did you have a spoon in your pocket?
Waiter: The utensil most commonly asked for is a spoon, so I keep a nice clean spoon in my pocket, in order to save time!
Man: That's very clever! And I've noticed you have a piece of string hanging from your fly, whats that for?
Waiter: In order to save time, I can unzip my fly with the string, go for a pee, and then I don't have to waste time washing my hands.
Man: That's very clever! But how do you manage to put your willy back in your trousers?
waiter: With a spoon!
