The Lesser of Two Evils?

Sam was just in his room playing with a Koosh ball. He had thrown it up on TJ's shelf and nearly knocked down one of TJ's model trucks. I told Sam he was not allowed to throw the Koosh ball, because he might break something. About five minutes later, I found Sam on his bed, trying to reach the top of TJ's dresser. On the dresser was the Koosh ball. I asked him what he was doing, and replied...

"Picking my nose."

He WAS doing that while he climbed on the bed. And he knows he is not supposed to do that. But he was attempting to distract me from the Koosh ball. Apparently, nose picking is the lesser of two evils in this case.
