Character mistake: When the "Honey Bees" (Mary Ann, Ginger, Mrs. Howell) perform, Mrs. Howell (Natalie Schafer) messes up her lip-syncing throughout the number.

Character mistake: Thorny tells Ozzie that Clara Randolph is throwing a party. When Ozzie tells David and Ricky about that party, he calls her "Mary Randolph."
Character mistake: Near the end, when Michael reveals to Brennen he knows everything about him, he says, "I know everything about Tyler Brennen."

Michael already knew Brennen's first name from the first time he met him, in Season 2, Episode 15 "Sins of Omission."
Character mistake: When Charlotte is looking at her wedding announcement in the New York Times, there is a close-up shot of part of the article. It says, in reference to Charlotte: "She is a writer and editor at Fashions Magazine in Manhattan". This is not true, nor has it ever been true. Perhaps the producers of the show threw that in, to see if anyone would notice. Also, the same article mentions: "The bride, who will be keeping her name..." and yet we never really hear Charlotte use the name York instead of Goldenblatt. (00:16:45)
G.I. Jessie - S2-E26
Character mistake: In the beginning of the pilot episode, Jessie told the cab driver that her father is in the Marine Corps. However, it is shown in this episode that her father is actually a lieutenant colonel in the Army. It's highly unlikely that Jessie wouldn't know what branch of the military her father was in considering how much she spoke about her military upbringing throughout the series.

But when Cooper arrives, he says, "Sorry for blowing off at you yesterday," which means another day has passed. However, at the Hannah concert, it is the same day all the while, so Cooper had got his days wrong.
The Joker's Flying Saucer - S3-E24
Character mistake: Vertigris tells Joker he planted a bomb in the Batmobile while it was parked in front of City Hall/Police HQ. Only in this instance, it wasn't. It was parked in the alley out back, the better to hide his bomb-planting from public view, so it's strange that he'd forget this. (00:08:15)
