Lol, how about a ski? Chain-o-Lakes in Illinois, all mud bottom, trying to get my foot back into the binding so I stood on ski and pushed my foot in the binding. Pull my leg up, foot popped out of the binding, ski stayed stuck in the mud. Never could find it.
More recently we were trying to ride in a chair on a disk--but we neglected to check if the chair floats.... Umm where did the chair go?
