Translation Please

As we were driving down the rode Grant is in the backseat (obviously) and says, "Mommy, I fell a dunk." Um What? And so he repeats it with a little more vigor for me. Once again, WHAT? This goes on for awhile then I change the subject because he is getting really irritated with me. Go to errands.........Coming back on the same road ..........

I say, "Yuck, do you smell that skunk?" Grant's reply, "Yeah, dat's what I said, I fell a dunk!"

Mystery solved!!
