Summer is almost over, which means the days of frying our brains at the beach and numbing our minds with action-packed blockbuster movies will soon be gone too. Let’s start revving up our brain cells with some intellectually stimulating activities this weekend — don’t worry we included some frivolous fun as well.

Friday Check out the Halsey Institute of Contemporary Art’s two new exhibits, Studio Practice and School of the Viking Spaniard Revisited, at the opening reception event tonight.

Comedy is also an art form. The Improv Smackdown at Theatre 99 has the audience select the winner — arty and participatory, that’s a win-win.

Before Bill Murray had a cult-following, he starred in Groundhog Day. See it under the stars on the Grand Lawn in Mt. Pleasant.

See Noel Coward’s comedy Fallen Angels about a love triangle amongst a group of friends at the Woolfe Street Playhouse. It’s also playing on Saturday if you can’t make it on Friday.

Saturday SpaceCraft Studios celebrates their first year in business with a crafting party and pop-up shop from Runaround Sue Vintage.

Stomp out your week’s frustrations on some grapes at the Tenth Annual Grape Stomp at Irvin~House Vineyards.

Charleston’s new improv group the Improvables have a show in Summerville.

Former UGA football coach Vince Dooley signs copies of his horticulture book at Magnolia Plantation and Gardens. 

Hootie‘s back in town — if you have tickets, enjoy! If not, maybe stroll around Daniel Island for some music al fresco.

Meet artist Jim Goulah at Art Mecca to keep your artistic juices flowing.

Sunday Some people treat their cars so well, that it’s an art form in itself. Stop by the Steel Pony Charity Ride and Car Show to see for yourself.

College football may not start until next week, but brush up on your SEC trivia at the Mellow Mushroom you’re prepared for the upcoming season.

And there’s one last chance to get your laugh on at the Tin Roof’s Open Mic Comedy night on Sunday.
