Skip the Emus, Aussies lost a war with them. Instead, pick up a Cassowary. Just remember, you have to try riding it in order to establish dominance.
Oh, they fly. They just have very limited range. Yeah, no, you don't. As much as I want to encourage you to do it and have your wife get it on video, they will beat the PeTA out of you.

Peacocks can get pissy and they don't let it go. When I was a kid in Germany one had it out for my mom. He chased us all over the damn zoo or park where ever we went for like 40 minutes. We'd turn a corner and BAM! There he was again, always one step ahead of us and start after my mom again. Little 5'3" German lady getting hassled by a Peacock. And yes he was trying to bite her. I saw this happen again a few years ago here in Florida.
