A joke for British steemians

Most British people will remember celebrity singing impression show "Stars in Their Eyes" hosted by Matthew Kelly. If you don't this won't make much sense.

"A man called Simon goes on "Stars in Their Eyes" and Matthew Kelly notices he's in a wheelchair.

Matthew asks, "What happened?"

"I was in a car crash with my uncle. He died and I had to have my legs amputated. But they saved my uncle's legs and grafted them onto me. In six months' time I will be able to walk again"

"That's amazing!" says Matthew. "Who are you going to be for us tonight then?"

"Tonight Matthew, I'm going to be.......Simon and half uncle!"
