Cover art for Interlude with Ludes lyrics by Them Crooked Vultures

"I'M TRAINED & LICENSED & ARMED TO THE TEETH" sounds like a reference to Dr. Gonzo from Fear and Loathing in Las Vegas.

He's trained and licensed (as a lawyer) and towards the beginning of this very drug-laden movie he says "we'll need to arm ourselves to the teeth".
