Okay, there are: Feuerschwanz (Fire tail/dick) for German funny medieval metal with songs like "Metnotstand I'm Märchenland" (Mead-shortage in fairyland) or "Dumme Frage, Saufgelage" (stupid question, booze-session) Alestorm for a pirate-y metal with song like "Mexico" (the title isn't a pun, but the song is funny) or "Zombies ate my pirate ship" Korpiklaani for the purest of drunken metal with songs to a lot of alcoholics including "Vodka", "Tequila", "Beer Beer" and more...
