10 Unexpected Breakout TV Characters
2. Frank Reynolds (It's Always Sunny In Philadelphia)
Watching too many episodes of It's Always Sunny in Philadelphia in a row plays havoc with your moral compass. Keep in mind that this show is about possibly the five worst people on the face of the Earth, running a bar in Philadelphia.
In season one, it was about the four worst people on the face of the Earth, running a bar in Philadelphia. Danny DeVito didn't join the cast as Frank Reynolds until the first episode of season two and in that moment the game changed. Frank started off as somewhat respectable businessman but gets dragged down into the muck by the gang. Now, he's the most reprehensible of them all, which is why fans love him so much. Frank is capable of anything.
