Traders will bet on anything :)
When I was at Morgan Stanley in the late 80s, we used to watch the marquee at a XXX theatre around the corner on 47th get the title of the headliner movie changed every Tuesday morning during the mid-morning lull and play it like Wheel Of Fortune: $10/letter, winner take all.
The only time I won, it was "Yank My Doodle!" and I got it on the 6th letter :-)
