An Old Man Calls In To A Radio Station During A Contest...

"Welcome to 99.5 The Lounge, you're on the air. We're currently holding our annual quiz contest; answer any of three questions right, and you'll win $500. You ready?"

"That I am."

"All right, let's begin. The first question is... What has four wheels and travels on roads?"

"That would be a car, right?"

"Almost, but not quite. The answer we were looking for is 'a Toyota Prius.' You still have two more chances for that $500, so it's okay. Let's move on to the next question, shall we? What guzzles gas, has four wheels, and can cut your lawn?"

"Why, that would be a lawn mower!"

"Close, but in particular we were looking for a Black and Decker 15" Corded Mower with Edge Max. You still have one more question and one more chance to get that $500."

"All right."

"The final question is... What transport vehicle flies using two wings?"

The older man goes silent for a second. When he comes back, he says: "A Boeing 747, final answer."

"Unfortunately, you were wrong. The answer we were looking for is "a plane"."
