I'm Rubber. You're Glue.

Every now and then I'll be driving down the road with the kids in the car and some childhood rhyme or playground taunt will pop into my head. I blurt it out of nowhere and my kids are amazed at the genius of my words. In the most recent case:

I'm rubber. You're glue. Whatever you say bounces off of me and sticks to you.

That was playground gold when I was a kid.
