Dave W had a spider living down behind the clocks in one of his bikes... it was quite a cutie ( I like spiders ) and he never got around to evicting it, well not until the day it decided to pop its head out from the clocks one day ( at around 80 mph ) and go for a wander around the bike.... it then got unceremoniously blown off ... poor little thing !
I generally like spiders as well though I react automatically to one getting near my face. However, my buddy was allergic to bee stings and he had a bee get under his helmet and sting him in the face at about 60 mph. He swelled up almost immediately and they almost had to radial saw the helmet off. They ended up prying it off, but it was a shed load of pain! I think he drove about 30 miles in this condition before getting to the infirmary. Huge cajones, that guy
