Rockin' Ronnie is a DJ for WLNF radio.
In "A Star Is Reborn", Stan uses CIA technology to override a telephone signal to be the tenth caller in a radio contest and wins a trip to Hollywood.
Ronnie provides commentary for The Langley Falls Bazooka Sharks radio broadcast in "The Long Bomb".
Stan does an in-station interview with Ronnie on 520 AM 'The Fist' to plug his new play Stomp in "Stompe le Monde". However, when Ronnie offers to give away tickets, Stan admits the show is already sold out, leaving Ronnie to try to figure out why the show needs advertising in the first place. Backed into a corner, Stan lashes out that Ronnie doesn't play Toad the Wet Sprocket and Ronnie admits it is because Toad slept with his wife.
While listening to the radio in "The Wondercabinet", Steve hears Rockin' Ronnie's radio show.
