Playing at the rec back in college...going for a loose ball, I poked some Asian guy in the guy. I physically felt my finger slide into his eye socket. I felt bad but it wasn't intentional. He was cool about it despite probably being blind in one eye now.
I was knocked the frick out on a vicious ball screen in the pi phi shoot out years ago. We were in the semis and losing, totally gassed, and not paying attention. Was following a guy down court...giant black dude who was a good 6-8 inches taller than me laid me out. All I remember is coming to one the sidelines with an ice pack on my neck.
