handrail on a 8 stair, hit a notch, fell knee first right into the stair, stood up to catch my breath with my hands on my knees and felt a HUGE hole where there shouldnt be one! pulled my pants up and yeah, there was my knee cap! long story short, 50 stiches inside my knee, 25 on the outside. then i was playing ultimate frisbee like a month later after my doctor cleared me and broke it open again, getting 50 more stiches with minimal novicain, HOLY SHIT OW.
