The Self-Destruct Button

Last night we went to Sam's Club to do a little shopping.  We went to the self-check out line and Soren and Gabe were behaving as usual... touching stuff, asking questions, etc.  Soren noticed a big green button on one of the conveyer belts that wasn't being used.  Amazingly enough he didn't touch it, but he asked the nearby attendant what it was.  She said it just moved the items along and she pushed it to show him.  He calmly said, "Oh, I thought it was the self-destruct button."  Sean and I and the attendant just laughed!  Another Phineas and Ferb reference!  Dr. Doofenschmirtz's "inators" almost always have a self-destruct button.  These boys don't miss much!
