Sometimes you wanna go where everybody knows your name, and sometimes you wanna go where everybody thinks your name is Jethro Tull. Exert your aqualung with today’s Groupon: for $10, you get $20 worth of drinks at 12 Volt Tavern in Arvada.

The bartenders at 12 Volt Tavern bolster its dive-bar cred with a daily two-for-one happy hour, pairing suds and spirits with a punk-rock-heavy jukebox that helped earn it Westword's Best Dive Bar in the ‘Burbs award in 2007. From 3 p.m. to 6 p.m., the daily happy hour lobs beer bottles ($2.75–$4.50) and cans ($2.25–$5.50) to those longing to grip longnecks or crush something other than Pringles cans against their heads. Draft beers ($2.75–$4.50) cascade from foam-flecked taps as imbibers sip to the refrain of rhythmically clacking pool balls and whizzing darts. Mad Dog 20/20 and its 10 electric libations glimmer and gleam over the bar’s pale light, headlining the top shelf of 12 Volt’s library of liquors and spirits ($3.75–$8). On weekends, local punk and rockabilly acts storm the intimate stage, blaring tunes that ricochet off the wall’s aluminum PBR signage and the ceiling’s bottle-cap frescos of Johnny Rotten’s boyhood pony (a cover charge applies to live shows).
