Pool sharks got their name for their intimidating presence, merciless devouring of inferiors, and ability to swim only within the safe confines of an inflatable pond. Splash around with deep-sea dodgers with today's Groupon: for $10, you get $20 worth of drinks and pool at Sharky's Billiards.

Sharky's Billiards welcomes masters of the felt to challenge one another to stuff pockets with solids and stripes seven days a week. Sunday–Thursday before 7 p.m., cue wielders can rack 'em up with the sun's assistance by staking claim on a table ($1.50/hour) and quenching cravings for a discounted domestic barley brew ($1+) or well drink ($2.75). From 7 p.m. until close, guests can squeeze in as many games as possible by nabbing an all-you-can-play table for $7.50. As the moon takes its nightly place, liquid courage becomes more precious ($1.75+ for beer; $3.75 for well drinks) and werewolves more bothersome. On Fridays and Saturdays after 7 p.m., weekend warriors can rent tables by the hour ($7.50) to show off knowledge of acute angles and techniques for drawing with cube-shaped chalk.
