Two Milk and a Buffalo

The fellow we've been talking to about a couple homes for he has for sale apparently hunts. On his wall are two elk, and a moose. Ezra is a little mixed up about his animals I think. He was sure that the elk were horses, and I still can't convince him the moose is not a buffalo.
The entire time we were at the guys house Ezra pointed to the wall and chanted "Milk, Buffalo?!" 'Milk' is as close to 'Elk' as he gets. So, the gentleman has two Milk and a Buffalo on his wall and had no idea till he met Ezra.
