The Toys R Us jingle of the 80s and 90s inspired parodies without end, most of which were fairly unkind. The most common one:
I don't wanna grow up, I'm a Special Ed kid,
My mom dropped me when I was young and look what she did!
The rest is sometimes filled in with lines and actions from the equally cruel "Clap Your Hands and Stomp Your Feet." While most adults come to realize that their playground songs were not unique, this is one of the ones that everyone seems to think their own scout troop invented. "I Come from (Your Camp Here) So Pity Me" is another that people tend to think is unique to their own school or camp. Actually, songs like this that were memorable enough for anyone to be talking about them years later seldom stayed put for long.
My own version, which I think I DID make up (though I could be wrong) was:
I don’t wanna grow up, I’m an A.D.D. kid
There’s a mil…..hey, what’s this?
