I want to write a funny song, but i don't know what kind of chords/licks can I play. I mean i know that the major chords are the "happy" chords, but are happier chords available? (like for the "sad" chords the a Ddim is sadder/eviler than a Dm).

Also, any idea with some lead line to make a song very funny. Of course i know it has a lot to do with the lyrics but that won't be a problem.
