As seen on: Diff'rent Strokes (NBC)
Portrayed by: Dan Cooksey
Here's one of the most annoying and unnecessary characters ever foisted upon the innocent public in television's history. Sam McKinney was shoved into the Diff'rent Strokes mix in the show's seventh season, years after it had anything left to say and people only cracked a tired, weary smirk when Gary Coleman's schtick was past it's cuteness expiration date.
And so entered whiny, aimless Sam. He got kidnapped in one of the show's desperate attempts to keep folks interested—unfortunately, they brought him back. The cane that was supposed to yank him offstage afterward never arrived.
