Tell us a joke daddy

Schuyler began the morning with "tell us a joke!" so I launched into the only age appropriate one I could think of:

DADDY: what do you call a deer with one eye?
SCHUYLER: Mexico!
Answer is supposed to be "No eye deer" i.e. no idea

Which may be the best response I've heard to that joke although I am not sure but something about the response seems vaguely racist.
