Kid logic is different than adult logic.
Three-year-old logic says that if they are playing musical instruments on TV, you MUST play along. And if you want to play a trumpet, the best place to get one is from the inside of a roll of paper towels. And all you have to do is remove all the paper towels from the roll and stuff them into the kitchen sink, tucking them in around the dirty dishes, and voila! You have a working trumpet!
I lose more paper towels that way. . . .
