I once had a wasp come in through the visor and lodge against my cheek, I stopped very quickly and while while taking the helmet off it dropped into the neck of my leather jacket and stung me.
I thought "what the hell" and gave the area a smack, so he stung me again and then several weaker times more as I pulled my jacket off as he was now in the arm of the jacket.
Jacket on the floor and he flew off.
I was not a happy biker.
If anyone saw this incident appx 25 years ago - NOW you know what was going on.
Another thing that makes bikers unhappy is the morons who flick their fagbuts out of the car window, I had one that mysteriously ended up down the back of my glove and I had a friend who had a crash because one ended up in his helmet.
It makes you wish that just once they forgot to open the window! j
