Both seem to have a sense of humor about their music and a real devotion to the importance of providing entertainment and not taking things too seriously. But with both it doesn't come with a sense of self-awareness, or an ability to laugh at themselves, at least not for the same reasons everyone else is laughing at them.

Of course, in Simmons this comes across as obnoxious, while with Kelly it's endearing. I guess because Simmons is so arrogant, where Kelly comes off as relatively humble.
