Say What?

Ty has been putting words together and it's kind of funny sometimes.  Take today, for example:

(Ty woke up from his nap shortly after hearing the front door open and close when Russell came home from school.)
Me: "Did you hear the door open?"
Ty: "Mmm-hmm." [His typical "yes" answer.]
Me: "Who do you think it was?  Who came in the door?"
Ty: "Uhh...cows."
Me: "Cows?!  Cows came in the door?"
Ty: "Mm-hmm."

Later, as I was recounting this conversation to Russell:
Russell: "Cows came in the door, Ty-Ty?"
Ty: "Nooo...bunny."
Russell: "A bunny came in the door?"
Ty: "Mmm-hmm!"

Later this evening:

Ty: [Seeing a car commercial on TV] "Hi.  Hi, car.  Hi, car.  Yub you."
I've never hear him voluntarily say "love you" before!  I guess he is his father's son...

I'm excited for more funny stuff to come out of his mouth!
