Hailed as "the best series running at this time" (thanks, Billy Brujo Show!), it's Grave Mood Rings.

Mixing vampire humor and 1970s tropes (like pet rocks, lava lamps, disco music, bell-bottom pants, mirror balls, and of course mood rings), the web series Grave Mood Rings pokes fast fun at classic slow-moving Gothic soap operas like Dark Shadows and the Canadian series Strange Paradise. In addition to a vampiric Viscount, a castle is home to a groovy Doctor (a phlebotomist, naturally), a jolly housekeeper with her own laugh track, a werewolf Vicar, and an arch-nemesis riddler wearing a Sphinx mask. Corny wordplay, the occasional bizarre sing-a-long, and haunted doughnuts punctuate the proceedings, in the tradition of the sketch comedy of MadTV, Kids in the Hall, and SCTV.  This episode was penned by Jonathan Caws-Elwitt.
