People at a bus stop often ask how long the wait until the next bus will be. “How long will the next bus be?” they ask.
 
“Same length as this one” is a joke reply from the bus driver or the bus dispatcher. The joke has been cited in print since at least 1927.
     
“Diner: Waiter, I’m in a hurry! Will the pancakes be long? Waiter: No, they’ll be round,” “Diner: Waiter, will my pizza be long? Waiter: No, sir, it will be round” and “Diner: How long will my spaghetti be? Waiter: I don’t know. We never measure it” are related jokes.

Heard This One?
Five times on the North Road had the tiresome old lady asked of the waiting inspector: “How long will the next ‘bus be, my man?”
 
And then he replied, “Same as the last one, 22 feet.”

I remember waiting for a bus many years ago in Salford. One came along full and the conductor was very harassed as people piled on. I got to the platform. he then shouted, “That’s the lot!” I said, “How long will the next bus be?” Without batting an eyelid he said, “Eighteen foot six, same as this one.” Then he rang the bell and the bus disappeared up the road.

And back to buses for a moment. I like the delightful reply to the lady’s question: “How long will the next bus be?” Replied the weary manager: “Exactly, madam, the same length as the last one.”

Off the field, folks are always saying smart-alec things to me. For instance, I was waiting on a bus the other day and asked a guy: “Say, mister, how long will the next bus be?”
 
And he replied: “I understand it’s going to be 32 feet and eight inches long.”

The England team stayed in the Park Avenue Hotel in the middle of Gothenburg. Glanville remembers Bobby Charlton, England’s 20-year-old attacking-midfield genius, only once telling a joke. It was in the lounge of the hotel, and it was about a bus queue in the north-east of England, where Charlton grew up. A man in the queue, who was unable to get on the bus, asked: “How long will the next bus be?” The bus conductor replied: “About as long as this one.”
