Yes, skits are fairly uncommon in sci fi cons. There are some contests that do have them, and are likely what inspired the skit trend in anime conventions.
That being said, I can admit that we gave our best in show award to a skit this year at Ikkicon, but it's difficult explaining to people that they didn't win because they were the best skit. There's allready a Best Skit award for that. They won because not only were their costumes damned impressive (Kingdom Hearts II group with a Sora, Riku, Schoolgirl Kairi, King Mickey fursuit!, and two very neat and clean Turks) but they also had something I like to talk about alot and that's STAGE PRESSENCE! EVERYONE payed attention to them, fans of the series or no. They COMMANDED the audience and it was awesome to behold.
