Ran over a squirrel while descending on my brand new bike. It was bam bam with both wheels and then he rolled for a bit then ran off the road. I hit one while riding my motorcycle as well. That was hit, go once around the sprockets and then get pitched into the median. He ran away too.

Last summer I was in the drops and cranking and ran over a groundhog's tail. I really thought I was going to hit it dead on and crash but just caught his tail. Their tails are very short so it was very close to disaster.
