Some points to consider:
1. In the years leading up to the mid 90's, America's Funniest Home Videos was all the rage (at least as I perceived it). During this time, it seems like at least 33% of the videos on that show were of men getting hit in the crotch by . . . something. Anything, really.
2. Video cameras were different back then. Not everyone had them, so when you got access to one with a blank tape, you had to act. Plop in a big 'ole VHS and shoot away.
This is the situation four friends friends found themselves in -- Charlie Knight, Brad Williams, John Huston, and myself (there may have been a separate cameraman, I don't remember.)
After at LEAST 13 years in the vault (my basement), this long lost classic has been, at last, found. Without further ado, I present, in all it's glory, the famous Crotch Injury Video.
