“Diner: Waiter, will my pizza be long? Waiter: No, sir, it will be round.”

A joke about ordering pizza in a restaurant is:
 
Diner: Waiter, will my pizza be long?
Waiter: No, sir, it will be round.
 
The joke was posted to the newsgroup alt.smokers.pipes on November 10, 2003.
 
“Diner: Waiter, I’m in a hurry! Will the pancakes be long? Waiter: No, they’ll be round” and “Diner: How long will my spaghetti be? Waiter: I don’t know. We never measure it” are similar jokes. “How long will the next bus be?”/“Same length as this one” is a related joke.

Half the customers never even got the joke. Just like now when after ordering a pizza they always ask: “how long will that be” my reply is ” It won’t, it will be round” Nothing ..crickets,  most of the time.. No sense of humor these people. whaaddayagunnado??
