Crazy Ex-Girlfriend has a song for everything: one-night stands, girl crushes, obsessing about something you've said and now…large breasts. That's right, get acquainted with "Heavy Boobs" in the video above.
In "Josh's Sister Is Getting Married!," the Monday, March 28 episode of The CW comedy, Rebecca (Rachel Bloom) gets pulled into a tricky situation with Josh's (Vincent Rodriguez III) family after his sister (Tess Paras) asks her to be bridesmaid. Rebecca decides to use the role to try and smooth things over with Valencia (Gabrielle Ruiz). While trying on dresses, Valencia comments on Rebecca's chest size, out of jealousy, but Rebecca is quick to point out big breasts aren't all they're cracked up to be and launches into "Heavy Boobs." It's something special.
