Where is the bathroom?
I... can't find anything wrong with this line of reasoning...
Where you left it! How'd you lose another one?!?! Geez! Wasn't it outside that pizza joint? I can't remember.
OK, now I don't know either. I'll just have to declare the corner of this room to be the new replacement!
Don't let me down like the other ones did, or you'll be sorrrrrry! ...
