This pair of Louisiana high school teachers were charged with "carnal knowledge of a juvenile." If you think "carnal knowledge" means they know his junk like the back of their hands, then you're absolutely right. Shelley Dufresne, 32, and Rachel Respess, 24, had a threesome with one of their 16-year-old students in Respess' home. The trio's tryst lasted over a year, and of course, was documented on video for keepsake. These naughty teachers were only caught when the student in question went around school bragging about his sexcapades.
