Rotten Egg

Today our family went to the mall to do some shopping. On the way back to the car Thomas announced, "First one there is a rotten egg". He procedded to run to the car giggling all the way. He ran full force into the car in his effort to win. I am assuming he learned this phrase at school, maybe he just didn't quite get it. As I recall the saying goes, last one there is a rotten egg, and maybe not the prize Thomas thinks it is. Maybe I should leave an egg out so Thomas knows what a rotten egg is, or maybe, just maybe I should let him go on for awhile being the "winner".
