Supposedly, they teach the socially awkward, how to be real men. Coach them on picking up women, and having a more active social life. However, if you listen to "Professor" describe it, it's more him admitting that has to be the center of attention, and it helps him get laid all the time. I have my doubts about the last claim, but I do believe that he is self absorbed enough that he forces himself to be the center of attention. Probably to a great deal of ridicule that he thinks are complements.
