Happens after you clog a toilet with a serious dump. As the bowl overflows, there is one little floater that stays inside the bowl and rides around the rim as the water still swirls from the prior flush.
Dang, I just stopped up your toilet. At least you've got a rim rider cruising around to cheer you up!
