What did I Teach this Boy?!!!!

I say some non intelligent things sometimes. Mostly to kid and get a reaction, but I have tried to cut down on that since Luke. Well when you get around friends and comments start flowing, some interesting things come out. My phrase for a little while was, "Keep talking and I'll knock your face!" Being wary of where my son is at all times I must have mentioned this at some point because he let me know today. I was walking back into our living room when I saw Luke chasing our dog Rocky. Rocky was trying to get away like usual, but this time Luke was close on his tail saying, "Rocky I'll knock your face. I'll knock your face." As he is warning Rocky he is swinging his arm to actually knock the other end of Rocky. I had to try and explain the best I could to a two year old that we don't say that, which is hypocritical on my part because I actually said it first. I honestly haven't said this for some time. I don't even know how he remembered this. All I can say is that we really have to watch what we say around this boy. Although he could make a nice robot if I program him correctly.
