Someone is trying to push Park Slope's organic locally sourced buttons.

"Coming soon" signs purporting to advertise new businesses such as Kale Kidz (The Chuck E. Cheese of Kale) and Green Sunsets Organic End-of-Life Planning have appeared recently in empty storefronts along Fifth Avenue.

Nice troll, Brooklyn. #slopelandia A photo posted by Krissa Corbett Cavouras (@petithiboux) on Nov 8, 2015 at 1:59pm PST

Some of the signs poke fun at well-worn Park Slope clichés such as the neighborhood's commitment to kale consumption.

Others seem designed to give stereotypical Park Slopers heart attacks: one claims that Donald Trump is setting up a campaign office in the neighborhood, another says seafood chain Red Lobster is opening soon.

I'm assuming this is a joke...#slopelandia A photo posted by Kate Krupa (@kkrup) on Nov 8, 2015 at 10:08am PST

Excellent trolling in the old Baluchi's storefront on 5th. #slopelandia A photo posted by Doug (@bklynspoke) on Nov 8, 2015 at 8:43am PST

The signs are tagged #Slopelandia, a reference to the TV comedy series "Portlandia," which parodies the lives of privileged, self-important Portland, Ore. residents.

Series co-creator Carrie Brownstein recently explained the show in terms that could also describe some facets of Park Slope.

"If we are hyper-concerned about organic versus local or how our coffee's made, these kinds of worries are just a privilege,” Brownstein said in an interview with the radio show Studio 360. "Sometimes I think that narcissism of small things can start to be corrosive.”
