The Sing Off

What are some songs to sing a capella?

For drama class, we all have to sing a song alone a capella, any ideas what I can sing? My voice is medium range, I'm not sure if im an alto or soprano or whatever because I don't take chorus. Any ideas would be appreciated very much! P.S. I'm a guy by the way. I wouldn't mind singing a funny song in a bad way too.
