I can tell that you have some.... qualms about skits. ;)
I too know about using your voice and making a presentation. I've seen enough to know that we wish we could scream at them to speak up!

And skits are to be actually funny, sometimes their joke is only an inside thing that no one else will get.

THe best skit I saw was called Anime Sells Out. and had mini commercials of anime characters eating doritos, making slogans for pop, and even diamonds. But the delivery was what made it wondeful!
