Last call: Don't let summer's last screen door slam before checking out Michael Gaughan's show. One of those smart guys who just want to have fun, Gaughan set his mind a-roaming and let his pen and brush follow, with predictably amusing results. More than 20 of his parody watercolors lampoon everything from ads to Old Master paintings to advice columns. A comedian by temperament and an artist-illustrator by trade, Gaughan lobs some of his best jokes at serious art like Piero Della Francesca's Renaissance portrait of the blunt-nosed Duke of Urbino, whose hat gets a modern makeover in "Federico da Montefeltro DEVO" (pictured). Even Gaughan's chihuahua Toby gets a cameo role in a riff on Marcel Duchamp's "Nude Descending a Staircase." And there are sly jokes about everything from smart water and smartphones to hairdressers, beets, alligators and muscle cars. Seriously fun stuff. (Ends Sept. 9, free.
