What are the weirdest things you've encountered so far in your career as a dancer? Does it attract it's own unique type of wackjobs, like most artforms? (am game artist, can confirm that industry also has some real pieces of work)
I haven't come across much wierd stuff myself, to be honest, though that may depend on what you'd consider wierd.
I suppose, I should start with the fact that there's professional dancing, and there's hobby dancing.
Hobby is when you take dance class to impress people at a club, to relax, or to just be in shape. It's not very demanding, you don't get to perform, you don't have to keep track of all the details when dancing, etc. Social dancing partly falls into this category, though that depends on where you live, I guess.
Professional dancing - which most people almost exclusively associate with ballet - is highly demanding, for either your time, strength, money, sometimes social life, or all this together. Here, you get to perform in front of people (mostly on stage, or in competitions), and you need to execute all figures (moves) properly, not to mention the psychological factors such as pressure and competitiveness.
As an art form, dance is quite underrated, partly because it's so easily available to just about anyone - just go to a club, and 'shake dat booty', and you're suddenly a dancer - partly because it doesn't yield products like paintings, statues, or music; and partly because it's also a sport, and many people can't tell which it is exactly.
Still, it's unfair, because the pressure can be extrememly high (watch the movie Black Swan, and you can get the idea of how messed up it can be to be a professional), you have to spend hours on end at the studio if you want to be any good (and even then, there' no guarantees), you have to keep track of what you eat and drink, and you have little-to-no social life (though these last two things depend on the type of dance you're practicing).
So yeah, hobby is fun and games whereas profession is pain and not always gain.
So if you wanna know about fruitcakes, there are no specific ones, other than the dancers themselves, because you'd have to be crazy to dedicate your life to such a demanding profession (that doesn't even always pay well anyway). Plus, being a guy, I don't get hit on, so a girl dancer would be of more help there.
