Wheels on a Bus

Ben's new song that I have to sing to him ALL the time is The Wheels on the Bus. His favorite part is when the wipers go swoosh swoosh swoosh. He likes to be the wipers and swoosh back and forth. However........mommy is tired of the song.

Ben: blah do de?
Mommy: sing to you?
Ben: Yes (with a HUGE smile)
mommy: sing sing sing
(after it done)
Ben:again?
mommy: again?
Ben: yeah (again with a huge smile)
