If you don't know, now ya know... This has to be one of the greatest moments in music history. This shit took off when the video came out.
Via KYM: "On May 19th, 2013, the YouTube account Live Without published the video "The Dennys Grand Slam," featuring the band performing at a Denny's on May 18th, 2013. Within six years, the post received more than 1.1 million views."
Sometime later, an alternate angle of the performance popped up on TikTok, and spread like a virus (again), all over the Internet. Surprised we haven't heard any dubstep remixes yet.
