Two year olds are good for many things, like being defiant and yelling "No!" then giving you the best snuggle ever. They are also good for discovering the funny, and sometimes absurd, aspects of language.
My two year old was jumping on his bed yelling, "Yeehaw! Yeehaw!" I'd never heard him say that before, so I asked if he was a cowboy.
He gave me a funny look and an "uh-huh" followed by "Moo! Moo! Momma, I'm a cow-boy! Moo!" Apparently his interpretation of the word cow-boy was a little different.
And my two year old, he spent the rest of the morning running around the house mooing.
