In the dozens (hundreds?) of Arkham games we've played, we had the fastest devour ever.
We were just finishing up the setup phase. I had picked Darrell Simmons, and was looking forward to finally getting to play him as a character. We drew the setup Mythos card -- and the first player had to draw two Innsmouth look cards. Now, in the last three months we've only had one instance when a player drew the Innsmouth look, so I felt very confident of my chances. The first card was safe, but the second...
Well, later that round my wife killed the Deep One that Darrel had become. She choose to place Darrel's marker on the Deep One, and liked to comment on how she killed me. It was pretty funny.

Yeah, we're using Rex as a coat rack.
