That sounds like the squirrel I almost got. I was coming home from work on a nice twisty road when a squirrel ran out. I wasn't trying to hit it but wasn't going to crash avoiding it.
It ran from the right side of the road and I left my left boot toe hit it's tail. It continued on it's way to the other side of the road.
I've hit numerous birds ( I really like my armored gear ) and some really nasty bugs. I remember one time I had just flipped down my visor when I hit a big ass bug that splattered all over my visor.
When I was young, dumb and "squidly", I was riding in a loose fitting tank top. I was doing about 70 mph when I rear ended a wasp in my left nipple. To say that hurt would be a gross understatement.
I locked up both tires and ripped what was left of the back end of the wasp out. I had a hollow spot there for a month.
Back when I was in my early teens, I was over at the neighbors and we were taking turns on his Yamaha 100 dirt bike going around the corn field.
He took extra long the one lap and when he came back, he was all dirty and scratched up from crashing. Turns out as he was going down next to the field, a groundhog ran out and started down the trail. He got the brilliant idea to run it over. Only problem was the front wheel "washed" out to the side as he ran it over and he crashed hard
