On Friday, American food culture gets its just desserts with the nationwide debut of Sausage Party, the widely anticipated animated comedy that dares to ask, “What if food had feelings?

The Sony Pictures release is the first R-rated computer-generated cartoon to hit the big screen, and it features an impressive cast of well-respected actors portraying various foulmouthed foodstuffs. Here are five things to know about this not-so-tasteful moment in cinematic history.

1. It all started with a talking-cupcake joke.

In an interview with the Los Angeles Times, actors Seth Rogen and Michael Cera, who both lend their voices to anthropomorphic hot dogs in the film, trace the story’s origin to an old joke told by fellow actor Jonah Hill: “Two cupcakes are in an oven. One turns to the other and says, ‘God, it’s hot in here, isn’t it?’ And the other one goes, ‘Oh, my God! It’s a talking cupcake!’”

2. The most distinctive voice belongs to a chatty bagel.

Of all the recognizable voices in the film, there is one that really stands out: actor Edward Norton. But it’s not his regular voice, as Rogen tells the Daily Beast: “[Norton’s] been a friend of ours for around 10 years — and when we first came up with the idea we told it to him and he said, ‘I want to be in it, and I want to play a bagel that sounds exactly like Woody Allen.’ And then he did the impression for us and we were like wow, that’s fucking incredible.”

3. The singing Irish potato is a harbinger of doom.

The movie’s plot involves various supermarket foods who fantasize about life after the shelf life — until the grim truth is finally revealed in a grisly kitchen scene. The first to meet his fate: a joyously crooning Irish potato who gets skinned alive in front of horrified fellow foodstuffs, as shown in the film’s original trailer:

4. Hot dogs and buns engage in predictable innuendo.

The film’s second trailer is less violent but more sexual, particularly with regard to the imagined courting rituals of packaged frankfurters and their bready counterparts. With Rogen and company running the show, you can reasonably expect this sort of ribald commentary to continue throughout the film.

5. The pita bread is….Brazilian?

In order to earn its R rating, instead of the more restrictive NC-17, the Motion Picture Association of America (MPAA) required the filmmakers to trim some things from the original cut — namely, the pubic hair of some amorous pita bread, according to the Independent.
