Samuel Vimes is personally responsible for my pair of good boots and he isn't even real.

I went mountain climbing on Saturday and the good boots saved my life. Sometimes it isn't about feeling the cobbles beneath your feet in the streets of Ankh-Morpor, but about the god damned sharp rocks climbing Mt. Erebus, and the fact that one slip means certain death.

Oh, and speaking of death, he loves mountain climbers. He doesn't even have to do his job.
