won £500

I won £500 on a radio competition this morning.
The DJ called me and said, "We are going live in a few seconds, I'm going to ask you what you're going to spend your money on and I want you to tell the listeners on air."

"Okay" I replied.

He said, "3...2....1..... Congratulations to Marc, our competition winner, what are you going to spend the money on?"

I said, "I'm going to spend it on air."
