Recently the family was at a hotel. I asked Danny to get me my shoes his reply was, "No. I can't. I'm naked." He was, in fact, naked at that point.
Several days later I asked him to do something:
Me: Danny, beer me!
Danny: No, I can't. I'm naked.
Me: (looking at him) No you aren't. You're totally wearing clothes.
Danny: Not anymore.
And then Danny was naked. In my living room. Naked as the day he was untimely ripp'd from mother's womb.
No, I can't. I'm naked.
You have to admit it's a pretty good excuse.
