The "musical episode" is practically a rite of passage for television shows. Almost all of our favorite series have done it — from "Buffy the Vampire Slayer" and "Xena: Warrior Princess" to "Scrubs" and "Grey's Anatomy." And now the stars of "Pretty Little Liars" are set to break into song on an upcoming episode of the beloved series. "All of [the cast members] have incredible hidden talents and singing happens to be one of them," said Oliver Goldstick, one of the show's executive producers. "I thought it was a shame that we didn't utilize that, and we found a way to platform it in one of the episodes in the last 10 [episodes of the series]." In honor of the upcoming "PLL" episode, Wonderwall.com rounded up more shows that have gotten the musical treatment over the years. Keep reading to take a look back!
During Season 6 of "Buffy the Vampire Slayer," a demon named Sweet places a spell on the people (and monsters) of Sunnydale that forces them to express themselves solely through song. The 2001 episode titled "Once More, with Feeling," which features all original music, is so popular among fans of the seminal series that there are sing-alongs of it at Comic-Con International every year.
During Season 6 of "Scrubs," a patient interprets speech as song due to an aneurysm in her temporal lobe. Thanks to her condition in the 2007 episode of the sitcom, which features all original music, we now have the song "Everything Comes Down to Poo" as performed by Zach Braff's J.D. and Donald Faison's Turk.
