After recently announcing their new album Post-Apocalypto and a six-episode animated series that will debut via their YouTube Channel, Jack Black and Kyle Gass, also known as Tenacious D, are at it again with a new Bob Ross parody clip. In the video entitled, “How to Draw With Tenacious D,” Black channels his inner Ross to draw a portrait of his very sexy bandmate Gass, skimpy undies and all.

Black tells viewers that we will “explore his body together” as he puts the paint down in lieu of the much more almighty (and permanent) Sharpie. Gass (dubbed here as “Kage”) exposes it all while Black takes extreme care in drawing his bandmate’s penis, which he then says resembles a “tuna can.” (I guess the only “happy little tree” here is Kyle’s own wood.)

Watch the clip here:
