Sister Christian from WJHC AM is speaking on Mick's truck radio and references the station and the song "Go Up Yonder on Yon Hill Over There" by Mike Feebly.
In WHJC AM, Vinnie looks at a religious sign in the bathroom featuring a skunk, shakes his head and says "moron," just like Forest Ranger Billy did after kicking the skunk in "The Hike".
The main character, Vinnie, spends the entire movie trying to get to the Whiskey A Go-Go to see his favorite childhood band HUGS. HUGS is a fictitious band first mentioned in the movie WJHC AM.
