While the actor and writer has since settled into a groove with the long-running series, there was a point where he was worried the show might have "peaked."

You can see Glenn Howerton in It’s Always Sunny in Philadelphia, which is now streaming with a Hulu subscription. The show returns for its 17th season on July 9th with its Abbott Elementary crossover episode, so make sure to check it out. The whole gang will be back, and I can safely say we can't wait to see them all together again.
