I've had a few...
Lady threw a cigarette out of her car window, it went right into my helmet(Visor up). Got stuck between my left ear and helmet, pulled over as quickly as possible. It took a few weeks for the smell of cigarettes and burnt hair to go away.
In college I was taking a final and kept hearing a buzz/vibration. When I finished my exam I finally realized what it was. I had a bee stuck between my t-shirt and undershirt. I handed in my exam, went straight outside and took my shirt off, and away went the bee.
Riding to work one morning on my KLR650 a cat ran right in front of me. Caught it dead center of the front wheel. I wasn't sure what happened to the cat until I rode in the next morning...squished cat, right where I hit it.
Riding to work on my KTM990A one morning in the car pool lane, the car in front of me swerved, I slowed down a bit but had no where to go, cars to the right, cement barrier to the left and a 10ft ladder laying across my lane. I was probably going 45mph at this point, I just leaned back and tried to wheelie over, which went better than I expected, I didn't wreck. Thank goodness for a dirt bike back ground.
