Visit the cool interiors of White Rock Lake’s Bath House Cultural Center for a Pegasus Theater production of The Coarse Actor Rises, a spoof of Michael Green’s book, The Art of Coarse Acting. You’ll be in for an evening of mistakes, miscues, and mayhem, goofs, gaffes, and guffaws, with all the actors forging ahead, convinced the audience won’t notice a thing. Say promoters, “It’s a celebration of inept but terribly earnest theatre at its finest.” Tickets run $10-$25. Shows are at 8 p.m. with matinees at 3 p.m. Visit the page for schedules and tickets.

The Dallas Arboretum knows you and you family don’t really want to be outdoors for extended periods this time of year unless you’re inside a cool body of water, which is why they offer Dollar Days all August, which makes the idea slightly more appealing. During no other month can you enjoy the arboretum’s fully bloomed beauty for such a bargain. Even sizzling temps don’t change the fact that it’s “one of the world’s most breathtaking gardens,” right? Visit dallasarboretum.org for details. The park is located at 8525 Garland Rd. Parking is still $5, by the way.
