You mean Buster de Body Crab
When I was in high school the entire school had an outbreak in 1967. It turned out that the lockers in both the girl's and boy's Gyms were infested. There were some stories of parents going off the rails with their daughters and not believing they weren't having sex. It was a couple of days before the source was tracked down and letters sent out from the school with the A-pionate 900? or something like that to treat it. They had to tent and gas the gyms. It is pretty horrifying to look down at your pubes and see them moving!
