He masturbated. Does that count?
One thing that is important to remember is to completely brush the crumbs out of your beard and rinse your mouth out before going to bed. I was awakened once in the Smokys by shouts from the bunk below me. A mouse had crawled up on top this guy's beard and was nibbling around. As for the poster who mentioned his daughter getting her hand bitten....I don't know how old she was, but my daughter is only just now starting to get fastidious about washing her hands and she's 15! Nothing like a little peanut butter residue on your fingers to entice the fearless shelter mice.

There isn't anything you can do to avoid mice in shelters really, perhaps the only thing would be to use a bug bivy or something like that but to be honest, most experienced hikers I know prefer camping regardless of the weather.
Although I often aim for shelters, it's mainly due to good campsites and water sources, and in the south bear cables to some degree, but I very rarely sleep in the shelter itself these days.
I remember one night I was in my tent and this group of hikers (weekenders) were walking up the trail and they saw my tent and were like "ah damn the shelter must be full" or something like that and they were just so delighted that the shelter was empty, something I just don't understand.
When I started hiking the AT in the 70's I do not remember there being many shelters and the few I came across were trashed and not usable. I use to hike until I felt it was time to stop. On a nice night I did not even set up a shelter, just slept on my top of my pad so I could watch the stars. I had to relocate one night and set up a tent when the mosquitoes came out.

Bears love people, they say we taste just like chicken.
Mostly, when it's quite cold, everyone lays very closely snuggling with each other in the center of the shelter. As long as someone isn't wet and very cold they are often invited to also snuggle. After awhile people start touching one another. The down starts to fly. It's disgusting, but in a good way.
