If that is the first thing that came to your mind, your mind is a whole lot cleaner than mine!
my first thought was Marth Bellamy repeating in her head over and over "I must not check out Jack's ass, I must not check out Jack's ass..." very sorry.
The only thing that comes to my mind is something like
"This happens when you don't mind your fingernails. Mine broke, when I had to break into my front door last night because I left the keys inside." not too good, but might be a start :D
