At an ROTC class that included Tiger frosh Melvin Booker, Jevon Crudup, Lamont Frazier and Reggie Smith. They, along with their classmates, were learning how to cross a creek by sliding on a rope, and first up for this exercise was point guard Booker. He hooked onto the rope. Crudup and Frazier, behind him, pulled it taut. Booker started off. But, with him on the front end of his journey, the 3,000-pound test line from which he hung suddenly snapped.
Booker fell only four feet and onto land, but the rope whiplashed back, smacked him in the mouth and knocked out three of his teeth. Crudup and Frazier, now pulling on a slack line, fell in a heap, and when they arose, Crudup had a sprained wrist and Frazier had a slight concussion after hitting his head on a rock. Frazier, however, was still aware enough to go searching in the mud for Booker`s teeth, which he found and returned. Booker then went off to the dentist, where he underwent 4 1/2 hours of oral surgery to get his mouth put back together.
