What sound does a zebra make?

I really wish I could have gotten a full picture of this chick, but I was on a very small metro car, she was about 14, and I looked like a total pedo-skeeze taking this picture. Seriously, I wasn't smooth at all.

That said, the bitch is wearing ill-fitting, saggy-assed, zebra-striped skinny jeans. I think the zebra community would be appalled and offended.
