Reminds me of my son and all the buds he grew up with. They gave each other a very hard time all their lives. My son is in his 50's now. After they were grown up, married and had kids, they gave each other's kids the very loudest toys they could find! Now some have grandkids to "work" with. Bunch of brats, eh? They have a ball.
That was a past Christmas. He was not happy :)
