'CHELLE: Are you sure there was no trace of Boomex here?
SCHLOCK: Not a sniff, and I sniffed everywhere. And I crawled into some strange, stinky places, too.

'CHELLE: Unless they cleaned up after themselves really well.
SCHLOCK: Trust me when I say that nobody here cleans up that well. Or often enough.
