Spooky is the most neglected of the five basic human emotions: spooky, joy, sorrow, grouchy, and wet. Get horror glands pumping with today’s Groupon: for $10, you get two admissions to the Monster Club Crawl on Saturday, October 15, from 7 p.m. to 2 a.m. (a $42 value).

The Monster Club Crawl unites costumed carousers for seven hours of food and drink specials, costume contests, and spirits sampling, providing VIP access to revelry at 10 of the spookiest bars and nightclubs in Minneapolis. With the Monster Crawl pass, patrons can begin the eerie evening with specialty starting-point events including the Monster Poker Tournament at Whisky Park (starting at 6 p.m.), or Roller Crawlers at Gay 90's. Elixir Lounge primes partygoers with $3 Michelob Golden Lite bottles in anticipation for the open crawl (starting at 10 p.m.) to bars including Ugly Mug, known for spine tingles of the sporting variety, and Aqua, which hosts a dance floor bathed in incandescent lighting and surrounded by pillars that never seem to blink. Nightclubs Bar Fly and Seven corral paranormal partiers during the closing crawl (12 a.m.), inviting patrons to unwind at a candlelit table or strut their stuff until 2 a.m., when all dance floors turn back into shuffleboard courts.
