14 Problems Only It's Always Sunny In Philadelphia Fans Will Understand

10. Sometimes Frank Is Revolting

Danny Devito was Always Sunny's saving grace: the show wasn't receiving high enough ratings by the end of the first series and was threatened to be axed unless a big name was brought in. Thank you Danny Devito for stepping in as small fat man Frank in series two and for saving the show. However; Frank, we need to have a chat. While you are ultimately hilarious and create chaos on a regular basis, your hygiene isn't always consistent. In fact, often Frank is downright disgusting. Like his burping. And his toupee. And his beer stained polo shirts. He's your hero; but he's still gross.
