Three boys in a car during a car wash is loud, bouncy, irritating...and should not be attempted without medication. If you are prepared, you will have fun, because they are having so much fun.
When the line is long and the weather is mild, they will eventually ask to stick their heads out of the sunroof. Just come to terms with the fact that they will not be able to fit all at once and fighting will ensue. This is where you might want to begin medicating.
Once everyone has had a chance to view the mysterious "top of the car" (oooohhhh, wow!) you can proceed into the car wash. They will act like it's the first time they were ever in a car wash and begin screaming and jumping around like a kangaroo on crack. Relax, it's normal, just medicate.
Once you've gotten yourself good and loopy, join in the fun!
Okay, it's time for your Sunday Funny. See you tomorrow!
