Last year I was riding my road bike, and some big insect flew into my mouth. I spit it out reflexively, and it hit my arm and stung me, because it was a honeybee.

Glad it didn't sting me inside my mouth.

Riding third in a pace line of three riders, and the rider in front of me screamed and veered out of line. Seems that the guy in front of him had farted, and the unfortunate second rider had inhaled the entire gaseous product before it had time to dilute itself with surrounding air.
