Basically the title. That Klingon Pop (K-Pop?) was so unexpected and funny. Such a good comedic timing. But that bit was too short compared to other songs in this episode. I am a little disappointed.
The Klingon boy band made the final cut, thankfully. However, they shot two versions of the Klingons, led by Bruce Horak as the Klingon captain. The second was opera. Ultimately, the opera take felt too close to the other singing. Luckily, the Klingon boy band won.
@enteroninternet That was hilariously unexpected when they did that, and it explained why the Klingons were so pissed off, considering how much they like their opera.
