Sampson's son Tim Sampson appeared on the FX show It's Always Sunny in Philadelphia season four episode "Sweet Dee Has a Heart Attack". The episode pays homage to Sampson's work as Chief Bromden in One Flew Over the Cuckoo's Nest; Tim plays "Tonto" after Frank (Danny DeVito) is mistaken as mentally incompetent and placed within a facility.[citation needed] Tim made a similar appearance in an elaborate Cuckoo's Nest parody set in a restaurant kitchen in the second series of the British sitcom Spaced.
