At the zoo my family wanted to see Okapi.

I'll be honest, I had to channel an American accent in my head to make sense of this one, I was quite confused for a moment.

I'm lost on this one.

Huh, this one went right over my head, but it turns out it's because I was pronouncing it "oh-kah-pee" in my head.

This might make the joke make sense if you, like me, had no idea what an okapi is.
