What's in the name?

Part I

Toothbrushes:

Whenever we ask Luke what he's doing and if he responds "I don't know", we know he's up to something he shouldn't be. 

So, Kev and I were in our bedroom and Luke was the bath tub in our bathroom, right off of our bedroom. It was oddly quiet.  We asked Luke what he was doing. His response: "I don't know". Kev asked him again, and again he said, "I don't know." Kev asking him again and he went really quiet again. Kev said "Luke - you tell me what you're doing". Luke said, "I'm cleaning the bathtub...and my butt...with your toothbrush".

Needless to say, that toothbrush was thrown away and the mystery is still unsolved as to how many times that has happened.
