Love it bro!!

Where's the joke? You know what a joke would be? A zebra who was adopted by lion parents having thanksgiving dinner with his adopted parents, who choose that moment to tell him he's adopted. Oh, and by the way, we're all eating your real parents right now. Mom lion: "Well Norman. I have good news and bad news. The good news as that we tracked down your biological parents. The BAD news, is that when I said we should have them for dinner, SOMEONE missed the point." (dad lion looks away and starts whistling). THAT would be a joke. This is not.

Uh... It would be funny if we knew what grevy's zebra was from the very beginning, without you telling us, but... well done
