In Season 1 Episode 9 "War of the Roses" when Becky is seen walking down the stairs into the kitchen, a voice exclaims, "Oh hey Lori." Lori Loughlin plays Becky in the series.
Mistakenly considered a goof: Nobody can be heard saying "Lori" in any form. The crowd noise is too loud. Anyone who thinks they hear it is just imagining it in their own mind, which has been shown to be common on Brain Games (2011)
As Aunt Becky walks down the kitchen stairs at the beginning of the episode, one of the actresses, greeted her with "Hey Lori," which is the name of the actress who plays Becky.
Becky says "After 28 years of marriage the only mystery is who's gonna unload the dishwasher." Jessie and Becky were married in February, 1991 in The Wedding: Part 2 (1991) so she's actually has only been married 25 years. Strange she would get that wrong. In Love Is in the Air (2016) Kimmy gets it right when she says she has planned the perfect weekend "... to celebrate 25 years of marriage."
