Riddle Me This

In the car today:

Timothy: Tristan, what do you call a cat that crosses the road to eat a dinosaur?

Tristan: I don't know. What?

Timothy: You tell me.

Tristan: Tell you what? I don't know.

Timothy: You're supposed to tell me. What do you call a cat.....

Tristan: How am I supposed to know what you call a cat that crosses the road to eat a dinosaur? You asked me.

Timothy: Oh forget it. (crossing his arms and scowling) You don't get it.

Tristan: (Laughing) I don't get what?

Me: Tristan, just drop it. He's mad enough.

Later on.

Tristan: Mom, what do you call a big cat that doesn't cost anything?

Me: I don't know. What?

Tristan: A free-lion.

Me: A what?

Tristan: Get it? A feline?

Me: Did you just make that up?

Tristan: Yep (smiling)

Pretty clever, huh?
