Did Anyone Guess?

I posted this photo a few days ago on the blog post about Nigerian Curry (me at the Ibadan Zoo).  Did anyone figure out who is allowed past the gate?  If you are having trouble, try saying it with a British accent (it was a British colony so they had a Nigerian version of a British accent).  Anyone got it?  Nope, then scroll down to the bottom and I'll reveal all. 

ZOO KEEPERS ONLY!!!   

Have a good weekend.
