Don't know if you have an Iphone or Ipod but my kids found this fun little app for when you are feeling frustrated.
It's called Action Movie, if you have a photo of someone you turn on action move and a series of disasters happen to that person.
In one my son takes a photo of me, then turns on action movie, all of a sudden a giant flaming meteroite falls on me.
It's funny, silly, and juvenille, but man what a stress reliever, we get lots of laughs out of it.
Hang in there, you are beating him at his stupid little game, it may only be a little at a time but you are definitely winning.
Big hugs,
Bill
