Laughter is the best medicine, though its effects often take one or two months to kick in when fighting seasonal allergies. Boost your immune system with today's Groupon: for $12, you get two tickets to Magooby's Joke House (up to a $30 value), located in Timonium. In addition, Groupon customers receive a $5 food and drink credit.

Every week, the Magooby's Joke House schedule features established national headliners, including comedians featured on HBO and Comedy Central. The venue's Timonium theater boasts table seating for almost 400 people, making it one of the largest comedy clubs on the East Coast. Cars find comfortable parking spots to wait in, free of charge, while their owners head inside for a preshow drink—no standing outside or knowing secret thumb-wrestling moves required. Light eats satisfy hunger pangs during side-splitting performances, including goodies such as the Loaded fries dripping with cheese and a dusting of bacon crisps ($7) or the Magooby's Smokehouse burger adorned with onion rings, american cheese and a tangy dollop of barbecue sauce ($9.50).
