Only on the musical rom-com Crazy Ex-Girlfriend can a ditty about double D’s be deliberately untitillating. “I like [my sexy songs] to have boner-killer moments,” jokes co-creator and star Rachel Bloom. “It was really important to me that this song would not come off as, ‘Look at me and my big boobs! I’m so sexy, oooh!’ I wanted it to invite women in.” It helps that the catchy tune — an ode to the perils of being top-heavy — had a strictly scientific inspiration: In high school, Bloom stumbled upon a video of a breast reduction surgery she couldn’t shake. “They cut open the boob, and I was just really struck by how it’s just fat,” she says.

So when the show tackled the literally weighty topic in its March 29 episode, Bloom made sure to include unsexy comparisons and painful choreography. In fact, filming the music video for “Heavy Boobs” was backbreaking work, as Bloom and her backup dancers swung their chests to the beat. “I felt so bad,” she admits. “I bought the dancers massages afterward.”

Here’s how Bloom shaped up the lyrics to her filthy, funny earworm about her “pair of monsters.” 

I got them heavy boobs, heavy boobs

Dense like dying stars

I got them heavy boobs, heavy boobs

I can’t run real far.

Celestial orbs have tons in common with, well, human ones — or so Bloom thought after an eighth-grade science class. “I was fascinated by white dwarf stars. They’re so dense with material,” she says. “When my boobs were getting big, I was like, ‘These are dense! Like a dying star!’ “

Let me break down what I just said

Each of my double D’s has the

Volume of a toddler’s head

Not bitchin’ ’bout my boobies

They look super fly in shirts

But if I swung them in your face

You’d be like, ‘Oh my God that hurts’

‘I’m blind, holy crap

I literally can’t see

I have permanent retinal damage

I’m suing you and your heavy boobies.’

Heavy boobs, heavy boobs…

A few years ago, Bloom’s own double D’s caused aches that discouraged her from dancing — a feeling she expresses through the violence in this lyric. “My boobs were a burden, because when they were painful, nothing would get done,” Bloom says. “It didn’t feel like my body.”


Here is a list of all the objects that

I can hold under my boobs:

Stapler, 10 pencils, paperback copy of

Arabian Nights

Dog bone, remote control, hard back copy

of Wuthering Heights

Thank Bette Midler for this one: On her short-lived sitcom Bette, characters joked about testing breast perkiness by putting a pencil under them, a scene that captivated the middle-school-aged Bloom. “Years later, I realized I could hold, like, my iPhone under my boob,” she marvels. The bridge became Bloom’s first joke written for the song, and the list came from Bloom experimenting with her own torso. “When I was home, I took off my shirt and walked around my office and saw what I could actually put under my boobs,” she says, adding that she managed to hold a paperback copy of Catcher in the Rye. (Because production couldn’t get the rights to the novel, Bloom swapped in Arabian Nights and Wuthering Heights.)


See, when a star is dying it transforms

into a red giant, and if the red giant does

not have enough mass to fuse carbon, an

inert mass of carbon and oxygen builds up

in the center, transforming into a dense

white dwarf. And yeah, that’s my boobs. 

That’s what my boobs are like.

When Bloom realized her “dying star” quip might not make sense to anyone other than, say, astronomers, she added another spoken-word bridge. The mini-lecture further helped the song spoof its inspiration: Beyoncé’s “Diva,” which similarly blends singing and rapping.

I got them heavy boobs, heavy boobs

Dense like a white dwarf.

I got them heavy boobs, heavy boobs

They’d be a catch at Fisherman’s Wharf.

If Bloom had the time (and, frankly, budget), she would have used more inventive music-video choreography for this rhyme. “Originally, [we wanted to show] people with fishing poles literally catching boobs like fish,” she says with a laugh.

I got them heavy boobs, heavy boobs

Don’t ever forget

That these heavy boobs, heavy boobs

Are just sacks of yellow fat

Like a stuffing of a couch

They’re just sacks of yellow fat

Technically meant to feed a baby

They’re just sacks of yellow fat.

How to end a song that deflates the idea of breast sexiness? Note why they exist at all. “I didn’t want to fixate on what boobs are for,” says Bloom, shown above with those famed sacks of yellow fat. “But I wanted to point out that they’re, like, baby faucets.” Aaaand we’ve achieved boner-killer! 

Crazy Ex-Girlfriend airs Mondays at 9 p.m. ET on The CW.
