minus the lying part this is actually pretty good

What makes a sexpert? Having sex more than once? Knowing how to get the most out of your partner? How can anyone judge how they are without being that person (or character)? It doesn't take a certificate to be able to teach. While job searching, I saw plenty of collage professor positions available, even for those with "life experience", which were actually more appreciated than someone who had a degree. Even though the uke put it out there as a joke, he is treating the situation as true. I don't see a lie in that. He never told the uke "why" he wanted to teach this. Is his reason worse than someone who would do this just for the money?
