Spider-Man: Homecoming has quickly become one of Sony Pictures’ most successful movies in its opening weekend — second only behind Spider-Man 3. It’s an impressive feat considering it’s the second reboot of the franchise in the last five years, but that just speaks to how strong Peter Parker, the mythos, and the supporting characters of the franchise are.

One of the main figures in Spider-Man’s life is his caretaker Aunt May, played in the new movie by Marisa Tomei.

But while the comics kept May’s character in the dark for many, many years regarding Parker’s heroic alter ego, Spider-Man: Homecoming reveals his extracurricular activities in a memorable closing scene in which May nearly drops the F-bomb.

“WHAT THE FU-” she says, and the film immediately cuts to the credits backed by the classic sounds of the Ramones. Tomei spoke about filming that scene and the difficulty it posed for the filmmakers.

“I think I said the whole word, and then they had to fine tune and fine tune,” she said in an interview with the Huffington Post.

For being the most teen-oriented Marvel Studios film so far, Spider-Man: Homecoming definitely toed the line in that scene and in another where some of Parker’s classmates play a game of “F, Marry, or Kill.” It’s not unlike Wolverine casually dropping an F-bomb in Hugh Jackman’s cameo appearance in X-Men: First Class.

But Marvel is very family friendly, except in the rare case when a couple of members of the Guardians of the Galaxy go on a killing spree set to the sounds of “Come A Little Bit Closer” by Jay & The Americans.

It’s pretty funny that they decide to push the envelope in this scene, and that Tomei’s take on Aunt May is the one to do it.

Spider-Man: Homecoming is in theaters now.
