This is bizarre, even for Collegehumor. Wow.
Oh, I see, this is a music video for a very odd band. The original YouTube link says:
Music video for 'Skeletons Having Sex on a Tin Roof' from Orphic Oxtra's new album Kebab Diskó. Out now on Record Records.
Music/Video/Remix: Bergrún Snæbjörnsdóttir
Choreography/Wardrobe: Sigrún Jónsdóttir
Loosely based on Swords of Chaos's 'Skeletons Having Sex on a Tin Roof', rendition by Bergrún Snæbjörnsdóttir and featuring Helgi R. Heiðarsson on saxophone.
Jazz musicians... God do they love their drugs!
