I've never hit anything, but my brother had a squirrel damage some spokes.

And at a previous job there was a group of 3-4 of us who would commute together, I startled a groundhog, that decided running across the MUP was a great choice, the guy behind me hit it. Didn't crash somehow, just hit it like a speed bump, then came to a stop and we all had a laugh at the wtf moment.
