Mazel-Tina - S4-E13
Corrected entry: When everyone refers to Tammy's party they're catering for, they refer to it as a bar mitzvah. Bar mitzvahs are for boys - they're called Bat mitzvahs for girls.
The Cook, the Steve, the Gayle, & Her Lover - S6-E6
Continuity mistake: In this episode, the whole family is surprised that Gayle is dating Mr. Frond. But in S6-E4, they know Gayle is dating Mr. Frond because Gayle is upset he went to his aunt's for Thanksgiving.
Suggested correction: That's because the episodes were aired out of order. This episode (production code 5ASA12) was produced before "Gayle Makin' Bob Sled" (production code 5ASA17). It's not a mistake for the show. The network decided to air the Halloween, Thanksgiving, and Christmas episodes first so they could air before the respective holidays.
Correction: They say "bat mitzvah" several times throughout the episode, never "bar mitzvah" (with the exception of a play on words when it's referred to as a "brat" mitzvah).
