"Bue-ing" Guy

We were in the car the other day and Ben trying to tell me something. I can pretty much communicate with him about most anything these days, but I could not for the life of me figure out what he wanted. He kept saying something about a "bue-ing guy". I asked him about several things that I thought he could mean: something blue, something new, something about blowing, etc, etc. I was not getting it - he knew it and I knew it. Eventually we just had to settle on that. The next day we were in the car and he had brought along a few of those little plastic green army guys. From the front seat I could hear him playing with his guys and then I heard it, "bue, bue, bue." It was his little army guys fighting...and it dawned on me: "bue-ing guy" meant his little army men. HA! Love it.
