word play jokes

A friend of mine told her husband they had a Catholic bird in their yard.

"A what? How do you know it's a Catholic bird?"

My girlfriend is fed up of my constant wordplay jokes.

I asked her, "What should I do to stop my addiction?"

She said, "Hey, whatever means necessary."

"No, no it doesn't," I said.

Why didn’t the sun go to college?

Because it already had a million degrees!
