The fourth season of It's Always Sunny in Philadelphia wraps up with a musical episode. Danny DeVito's character, Frank, plays the troll who lets the Night Man into the boy's hole.

"You know, you've got to pay the troll toll if you want to get into this boy's hole," DeVito explained. "That's the thing. Soul, soul. He's laughing over there. I said boy's soul. You want to pay the toll and then get into the boy's hole."
The episode may be DeVito's first public musical experience, but he is well rehearsed. "I've done a lot of musicals. I did almost every musical that's ever been on Broadway in my shower. It's cool because I am a product of the love generation and I do all my work nude."
Frank may be a lowlife schemer but DeVito is mellow in real life. "I just go moment to moment. I'm very fortunate because I have greatness showered on me every day. I don't really have to do much to do that. I just be me and I'm happy about that. I don't do anything crazy. I'm not a wild person. I'm really tame."
