Kevin McHale has opened up about the Glee episode he calls his "actual breaking point."The actor starred as Artie Abrams, one of the members of William McKinley High's glee club the New Directions in all six seasons of the show. And yet, McHale opened up even more in the latest episode of his Glee recap podcast cohosted alongside Jenna Ushkowitz (who played Tina Cohen-Chang on the show).The two cohosts of And That's What You REALLY Missed podcast discussed an episode from season 5 of Glee titled "Previously Unaired Christmas" with McHale revealing that this episode was his "actual breaking point" while working on the show.Many fans consider this to be one of the most outrageous episodes in Glee history. For instance, this episode includes Rachel, Kurt and Santana inhaling helium to sing "Christmas Don't Be Late" before getting robbed by a sexy Santa; Marley, Unique, and Tina singing The Supremes' "Love Child" with Unique dressed up as pregnant Virgin Mary; and a live nativity scene where Becky, a student with Down syndrome, played Jesus as a baby.McHale offered an apology to anyone who was on set while he was filming the Nativity scene in particular."My mustache was causing some sort of allergic reaction, and I was itchy and upset, and it was late at night," he said. "[I'm] not proud, but I remember when that number came up, I was like, 'What are we doing?'"Back then, news outlets reported that this Glee episode was "too problematic" to air. As a result, the entire episode was recut into the version that aired on TV and fans have gotten to see.Ushkowitz pointed to the version of Harry Belafonte's "Mary's Boy Child" that she performed alongside Marley and Unique in the episode as a low point."It was like you had to commit so hard, because it was so bad. That's what I felt like in this number," the actress said."But that's the thing: I don't think it's supposed to be bad," McHale said. "It's supposed to be controversial But I mean, bad is good when it's funny. But I didn't think this was good this just felt like being controversial for controversial."Ushkowitz added that she "hated this song so much." She also hated "everything in this episode.""I was so angry in everything in this episode," the actress revealed. "But yet like, watching it, I'm like, 'This is ridiculous,' and it's so funny to me; I couldn't stop laughing during 'Mary's Boy Child.' And I hated the number so much. I didn't want to be there, but I had fun doing it because the stakes were so low at that point, right?"Listen to new episodes of And That's What You REALLY Missed on all podcast streaming services.See on Instagram
