I… don’t think… you understand what the point of classes are? They are supposed to be for people who aren’t good at the thing, so they can get better!
Anyway, yeah. Classes in ballroom dancing. That was the tried-and-true way to meet chicks at my very-lopsided-gender-ratio technical school. Like @puzzlegal said, there’s a shortage of men (so any lack of skill will be excused), and women like it! (Indeed, I would go so far as to say that most women find a guy who can dance – or is learning how to dance – rather romantic!)
