The Simpsons : Giant Mistake in Old Episode

Producer spots photo of Maggie in episode about Marge being pregnant with Maggie

The Simpsons executive producer Matt Selman has spotted a glaring episode in one of the show’s most significant episodes.

Vintage Simpsons fans will recall that ‘And Maggie Makes Three’ is the season six episode where Marge informs Homer that she’s pregnant with the youngest of their brood. But as Selman points out, there’s just one problem. In the very scene where Marge reveals the news, there’s a framed photo of Maggie in the background.

Selman posted the gaffe on Twitter, and it’s causing quite the debate among Simpsons devotees.

He later joked that seventeen people had been sacked for the blunder.

Selman joined The Simpsons in 1997, and has remained a strong presence on the series ever since. The animated comedy reached a historic milestone this past season by surpassing Gunsmoke in the total number of episodes. Currently sitting at 639 episodes, The Simpsons is one of the most influential television series of all time, and is expected to continue on at least until season 31.
