On The Bob Newhart Show, the Season 1 Christmas episode had a wreath in place of the MTM ribbon.
A variant from the 3rd season of The Mary Tyler Moore Show on an episode of Put on a Happy Face, featuring Moore herself replacing Mimsie, She says "That's all folks" in the style of Porky Pig from the end of the Looney Tunes cartoons from 1937 to 1946.
On Remington Steele (1982-1987), Mimsie wears a Sherlock Holmes deerstalker hat, and meerschaum pipe in its mouth. As it begins to meow, the pipe falls out of its mouth, and lands in front of the word "PRODUCTIONS".
On St. Elsewhere (1982-1988), Mimsie wears a scrub suit and surgical mask, which is animated to look like a mouth that is moving underneath when she meows.
On Bay City Blues (1983), an animated Mimsie wears a baseball hat, and a baseball glove in her paw. She catches the baseball in the air when she meows.
Just Between Friends (1986)
A variant from original prints of the final episode of St. Elsewhere. Fans have described this variant as the saddest logo ever, due to Mimsie flatlining and dying. Mimsie eventually died in real life shortly after this episode aired, with MTM Enterprises officially ceasing all operations a decade later.
