What's Lurking in Bubba's Closet

As most of you know, I'm preparing to move to Atlanta, Georgia. I've been very busy packing and trying to make the house look presentable for potential buyers. (That's a good trick with the kids and all the pets!)  Yesterday, I tackled my son's closet.  As I went through it, I discovered an old package of Swiss cheese lying on the ground. There were also some paper plates and an unopened can of tuna.  When the boy came home from school, I asked him about it.

"Bubba, what was up with the old cheese and fish in your closet?"

"Oh.  Yeah.  I forgot about that.  My friend and I were hungry so we had a picnic."

"In your closet?"

"Yeah, Mama.  It was nice and cozy in there, and nobody bothered us."

"Great.  Next time, eat in the kitchen, because if you don't, rats are going to invade your closet.  And then  monsters are going to come to eat the rats.  And then aliens are going to come to take the monsters to a distant planet. And then there's going to be an intergalactic war, and the universe is going to be destroyed.  All because you had a picnic in your closet!"
