I don't know about "on purpose," but these cagers sure are dull when it comes to life-forms that exist outside the steel-and-glass cage.
I remember crouching with my huge umbrella as a shield while walking by a 25 ft. puddle. It worked, but I don't carry one on my bike.
Another time (chalk it up to my own stupidity) I got some oily water in my mouth. Yuck.
(All this was as a pedestrian--the lowest order of the food chain.)
