Songfacts®:

• Pomplamoose lead singer Nataly Dawn channels Meadow Soprano on this song where she lets Johnny know that breaking up with her comes with certain risks. She's part of a "family business" that looks after each other, and they might just bust his kneecaps if he goes through with it.
  
  Dawn doesn't really have mob ties - her parents are missionaries.
• The song has a '60s throwback feel, evoking girl groups like The Shirelles and The Shangri-Las. Many songs from this era feature a Johnny.
• Pomplamoose was an early YouTube sensation, launching in 2008 and earning millions of views for their "VideoSongs" where they show how every sound is made. Unlike most YouTube sensations, they were still going strong in 2011 when they released "Bust Your Knee Caps," which became one of their most popular songs. In fact, they made a nice living doing it and never signed on with a management firm or record company. Over the next few years, they expanded their operation, bringing in outside musicians, producers and editors, but they kept it intimate and fun. In 2013 they found a new revenue stream when Nataly Dawn's partner in Pomplamoose, Jack Conte, co-founded the crowdfunding platform Patreon. Pomplamoose were one of the original artists on the platform and quickly turned many of their YouTube subscribers into members paying for monthly subscriptions. If any patron missed a payment, they would BUST THEIR KNEE CAPS! (not really)
• Many Pomplamoose songs are covers or mashups, but they do write and perform original songs like "Bust Your Knee Caps," which are almost always lighthearted tunes. Nataly Dawn also records as a solo artist, her outlet for more personal and introspective songs. In a Songfacts interview with Dawn, she talked about her solo material vs. Pomplamoose.
  
  "I love both projects," she said. "I definitely feel like Pomplamoose is a collaboration way more than my solo project just in terms of writing. I go to Jack and I've got a melody and bassline. He sits down at the piano and fills it out with chords and figures out the production and arrangement. He mixes it and it's really us coming to the table with our strengths and leaving space for the other person to do what they do best.
  
  It's a very different type of thing than sitting in my room by myself and plunking on my guitar. It's a very different songwriting process and very different recording process, but I love both of them."
• "Bust Your Knee Caps" surged in popularity when it started trending on TikTok in 2021. The TikTok version opens with the lines, "The day he left was the day I died," a snippet of dialogue from the 2016 horror movie The Love Witch. It then goes into the first lines of the Pomplamoose song:
  
  Jonny don't leave me
  You said you'd love me forever
  
  Addison Rae, Charli D'Amelio, and other top Tokers have made videos to it, transitioning from the movie dialogue into the song with a big reveal.
