Good bump up
I must have some injuries myself, but the first thing that comes to mind is one I inflicted on someone else, when I stood on Tom Shippey's toes, heh. I was laughing and not paying attention and stepped back onto him - I was embarrassed and he was very gracious
I also greeted Tolkien's grand-daughter while partaking of the brewer's finest so I inflicted a load of beer and tobacco breath on her.
