The ultimate put-upon priest isn't played by Macaulay Culkin but is instead portrayed by actor, writer, and producer David Hornsby. Hornsby has known the "It's Always Sunny" guys for some time and helps write and co-produce the series in addition to playing Cricks. He wrote such bangers as "The D.E.N.N.I.S. System," the brilliant two-parter "The Gang Goes to Hell," and even "Charlie Rules the World," an episode that had its own video game tie-in for a time. In fact, the "Sunny" folks like working with Hornsby so much (and vice-versa) that he's also a big part of Rob McElhenney's Apple TV+ series, "Mythic Quest," where he plays video game executive producer David Brittlesbee.

Hornsby has a long list of credits outside of his work with the "Sunny" team, including a regular guest role on the NBC crime-comedy series "Good Girls," film roles in movies like "Flags of Our Fathers," and a whole lot of great voice acting in animation. Hornsby is a talented creative who does a lot of great work, but when it comes to Rickety Cricket, sometimes he just doesn't get the credit, and people think Culkin plays the Catholic disaster. He doesn't, although he has been pretty busy lately!
