Glad to hear you're healing well Prof
Great to hear you're on the mend and back to the world of the sly, professor.
Glad to hear all is well....sounds like you got off luck! I scraped my head at the gym about 9 months ago and that spot STILL is a slightly different color than the rest of the noggin'!
Bet it felt great to be nice, slick and SLY again! I'll make a big effort to take care of my shiny dome!
