So We're Having Cow Butt for Dinner?

I bought a roast for Sunday dinner. Mckenzie read the label on the meat "rump roast." Rump roast mom? What part of the cow does this come from? It comes from the back end of the cow. You mean the butt? I suppose so. A long discussion then ensued about the fact that we would be eating cow butt for dinner. We discussed about the fact that when you buy pork butt it actually says "pork butt" on the label. Austin of course was not into any animal butt and Katie and Mckenzie laughed their way through the entire conversation. I didn't realize though that Emily had been listening to this entire conversation and a few hours later she said..."Umm, so mom, we're having cow butt for dinner?"
