Not the common Shin-Meet-Pedal, but the thing where you're in the air, and leaning to the side, so you take your foot off the pedal to catch yourself when you land... Only when you land, foot hits the ground, and sticks in place, bike keeps rollin', and the pedal gets you right behind the knee!
Had that happen before. Big piece of flesh(1" X 1/2" X 1/4" thick), hangin' off... Everybody tellin' me, "You need to get to the hospitol, that needs stitches". "f*ck THAT!" "Gimme my nail-clippers!" Snip Snip!(nirves were already severed, so I didn't even feel it) Bandage it up, wait about a week, it's all good!
