OK, what’s the joke?
That big bearded character in the image is the late British actor Sebastian Cabot, who was a main character in a late 1960s sitcom called "A Family Affair." In that series, he played the butler to an upscale urban bachelor who inherited (or adopted) two young children who are also seen in the image.
The butler's name was Giles French, mostly referred to as "Mr. French."
Get it?
