That fly thing reminds me of a guy I knew in college. Good guy, but a little twisted.
The barracks that we lived in were not built on slab foundations - they had a crawlspace underneath them for utilities and such - and some of the rooms had trapdoors in the floors to go down to the crawlspaces.
Well, Brian caught all the cockroaches he could (although because Charleston is such a genteel sort of place, they call them 'palmetto bugs' instead of cockroaches), and come Christmas time, he pinned them to his wall ... 9 of them in a row, connected with thread, with a 10th sitting in a tiny paper sleigh wearing a red hat and a big cotton beard. The lead roach in the string had it's head painted red.
Strange guy, but a good friend.
