This episode instantly brings to mind the 2009 anime masterpiece Redline-watch it on YouTube, and you'll see exactly what I mean.
It perfectly distills the most exhilarating elements to create an absolute thrill ride. The relentless bass drum pounds away until it drives you to the edge, the scratchy-voiced commentator adds to the chaos, and the shot of Mordecai and Rigby's faces getting blown back at face-melting speed is pure gold. Even the quirky German guys somehow fit seamlessly into the wild, over-the-top aesthetic.
If you're into high-octane, adrenaline-fueled animation, this episode is a must-watch.
