Buddha?

I have no idea if this is his idea of a bad joke, or some serious cross-cultural knowledge acquired at preschool. Today as we were getting into car, the Dude (age 4) says, "Daddy, What do you call an Indian with big ears?" I didn't know what to say. Couldn't recall any Indians (Native Americans or others) in the Scooby Doo or Rescue Hero videos, so I said, "I don't know, what do you call an Indian with big ears?"

"Buddha," he said.

Sometimes I have no idea where he gets things.
