The Fast Show, a UK broken comedy sketch show much loved by Johnny Depp (https://en.wikipedia.org/wiki/The_Fast_Show), had a few quirky spin-offs led by recurring characters:
"*In 2001, Ron Manager, Tommy and the interviewer fronted a comedy panel game show on Sky 1 called “Jumpers for Goalposts”. The interviewer was the presenter while Ron Manager and Tommy were the resident team captains.
Swiss Toni did a stand-alone series in 2003 and 2004 and broadcast on BBC Three*."
Not quite a spin-off but also odd, “In Pirates of the Caribbean: The Curse of the Black Pearl, Jack Sparrow quotes the show, the Rowley Birkin line “… and then they made me their chief!”. In a deleted scene of the movie, Sparrow also uses the Mark Williams catchphrase "I’ll get me coat.” "
