A person who says they can draw anything, but they probably just drew something and called it anything.

I can draw anything, even a dinosaur. (It had a head and a tail, and a question mark.)

I can draw anything, even a bird. (It looked like a confused pencil.)

I can draw anything, even a butterfly. (It had three wings and a bad attitude.)
