Sometimes, it's just like Theatre

Just like Acient greek Theatre, Skits often fall into two Catogories; Comedies and Tragedies. The Comedies are deeply thought out, full of live and usually contain, a Romance of some kind - Usually Yaoi. The 'Tragedies' tend to be taken from the original stroyline, because writing out a Tragedy can be quite hard - you are inventing an entirely new chapter of the original story for the Chracters to act out, whereas Comedies can be taken aside from the Original Storyline. There are some good examples of this.

This really is one of the Finest examples of a 'Tragedy' I have found. Taken from the Storyline of Full Metal Alchemist (Which is a pretty heart wrenching Series as it is) This is the devistating scene of Shou Tucker, The Sewing Life Alchmist, and his Family.
The Audience's reaction is imediate. Seeing the Chracters walk onto to stage is enough to make them gasp in Horror - infact one guy actually says "Oh God No!". The Cosplayers here have cleverly picked a Scene that will evoke a Reaction. The Music they've used is 'Brother' from the Anime, which, frankly, is Pretty depressing on it's own. One of the things that really makes this skit for me is the Chimera. It looks so cool! The Audience's reaction in this pretty sums up how I feel here. It's heart wrenching stuff.

Now that you're all horribly depressed, here's an totally Awesome Comedy.
This is a Naruto Skit. Techinically, this isn't apart of the Series, this is a Sketch where the Characters are at School, rather than being Ninjas. They're dressed in school Uniform and Basically use the well known Chracters to write Jokes around. Jokes that Work! There's your custom Yaoi couple in the form of Naruto and Kiba. Itachi Bullies Sasuke, and Sakura is as annoying as ever. I like the idea of having Chracters not in their traditional Outfits. You can find examples of this all over the place, some of my favorite examples come from Kingdom Hearts, where members of Organisation XIII are dressed as what they might look like if they took a Trip to Halloween Town, or the Pride Lands. I suggest you google it, or look on Deviantart if you're intrested because the People over there are Really good cosplayers. (If you've got a Picture of Yourself Cosplaying, I'd love to put it here.)
