You think you're the main event, but you're just a nobody with a loud mouth.

I'm the main event, not some guy who thought he could be in the show.

I'm the main act, not some person who thinks they're important because they talked too much.

I'm the big deal, not some nobody who thinks they're famous just because they made noise.
