Take the theme song of your favorite show and prioritize it around a specific character. As if it is being sang by or about him or her. What perspective do they have. If the theme song has no lyrics, make some up. It has to be to the tune of the show. Try to make it as unique to that character as you can. Most importantly have fun with it. Bonus points to whoever can do it in the characters voice.

P.S. I apologize for the example I can’t really sing and lost my voice due to a cold.
