12 Most Hilarious End Credit Bloopers In Movie History

"This is 40," a 2012 comedy written and directed by Judd Apatow, also features a single scene's outtakes over the end credits. The film mostly centers on Paul Rudd and Leslie Mann, reprising their characters from Apatow's "Knocked Up," Pete and Debbie, as they grapple with parenthood, relationship issues, and their careers. "This is 40" also features an incredibly robust supporting cast, including Megan Fox, John Lithgow, Jason Segel, Lena Dunham, and Chris O'Dowd, but one of them shines the brightest.

That supporting actor is Melissa McCarthy, who in 2012 was rolling on the huge success of "Bridesmaids" released the previous year. Her appearance in "This is 40" would be a precursor to her reign in studio comedies throughout the 2010s, including "Identity Thief," "Spy," and the "Ghostbusters" reboot. In "This is 40," however, McCarthy plays Catherine, a fellow parent at Pete and Debbie's children's school who files a complaint with the principal for their daughters' behavior.

In the outtakes, McCarthy goes on a rampaging improvisation about her violent urges towards the two stoic parents, which frequently causes Rudd and Mann to break character. Most of what she says is too NSFW to republish, but the outtakes are a delight, and perhaps even the funniest part of the entire movie. If McCarthy had any proof she could rule 2010s comedy, it was through these end-credits bloopers.
