It's Always Sunny In Philadelphia Quiz: Frank Reynolds - What's His Next Line?

Despite garnering a positive critical response when it debuted in August of 2005, It's Always Sunny in Philadelphia came perilously close to getting cancelled after its first season, as a result of low initial viewership numbers.

The studio argued that bringing in a big name would help turn things around. Many were interviewed but the cast and crew eventually settled on veteran comedy actor Danny DeVito. More than a decade later, it's safe to say that the decision has paid off.

DeVito's Frank Reynolds is an absolute comedic icon, to the point where he is arguably the most widely associated character with the cult show. Despite being a well established actor at the time of his casting, it is the role that he took in his sixties that he is most recognisable for to date.

Taking levels of maniacal depravity to never-before-seen levels, Frank's turns as the Troll Toll, the Trashman and the Warthog are the stuff of legend. Central to his success is DeVito's ability to produce an endless array of instantly quotable one liners that have steadily filtered into pop culture; even if you've never seen It's Sunny, the chances are that you will have seen it in a meme somewhere.
