If they were up your ass you would know where they were.
Sorry, I heard that expression one when somebody said they were looking for something (a lunch tray) and this hillbilly roughneck said "If it was up your ass you'd know where it was." I laughed really hard, and whenever someone says they're looking for something, I always think that, but can't say it out loud.
So, uh...
I always liked the ML1 Iron Man, personally.
ML 1 Iron Man and ML 1 Cap are excellent. The line was never better, I don't think.
