I'm trying to remember the name of a 1980's movie. It starts with a guy who's working selling some kind of wax on the beach and his buddy working a burger joint. They quit their jobs and decide to start their own buisness teaching guys how to pick up girls. Three hardcore nerds give them a bunch of money to just give them lessons every day and the main guys is trying to hide it from the girl he's fallen for and bla bla bla.
I used to watch it on Cinemax all the time and I can't think of the name to save my life. Someting with summer or beach in the title? I'm sure it's out of print but I'd like to try and find it on eBay... if I could get the name.
