Maybe all that dough went to their heads.

A young green-thumbed couple from Ohio allegedly made off with wads of Benjamins after discreetly slipping a bank teller a stick-up note.

The teller, working on August 24 at Savings Bank in Ashville, Ohio, complied—and in an instant, cops say, Josh Mogan, 28, and his blond 24-year-old siren sidekick Ashley Duboe were loaded.

The robbers managed to pull off the heist almost unscathed, save for the security camera image that showed a stone-faced man (apparently Mogan, sans his distinct face and body art) tucked in a black hoodie, wearing white gloves and carefully clenching the cash.

That’s all cops in Ashville, Ohio, had to go on.

But what’s the fun of bank robbing if you can’t share it with your friends and family on Facebook?

The tatted-up duo posted pics of themselves boasting ear-to-ear grins as they hugged by the women’s restroom; and embracing while Mogan (his face revealing his “Loyalty’s Thin” and “Betrayal’s Thick” tattoos) flashed bundles of cash. Mogan’s mouth couldn’t even get around the cash burrito he’d hand-rolled and wadded into his mouth. There’s Mogan again, this time resting his head on what appears to be a $1,000 cash pillow.

The lovers evidently wanted others to see them living the dream.

The harebrained frontman even started rapping to pals about their alleged score.

Mogan admits to one of his Facebook friends that he’s made it: “That’s called a McStack,” he responds, clearly referring to the bills folded in his big mouth. “I got six bands bra real s--- n---. I’m doing rrree+aaaalll) good,” the post says.

Sure, Mogan’s buddies may have been getting jealous. But Ashville was also watching and wanted in on the action, too.

Soon enough, cops say they caught up to the grinning grifters.

And they’re still mugging for cameras.

Only this time it’s for Pickaway Sheriff’s Office. The grins are gone. Their smiles have been switched out with sobering, blank stares while donning not-so-flashy orange jumpsuits. (The Sheriff’s Office did not respond to requests for comment by press time.)

Mogan may wish he’d kept his mouth empty of cash wads; authorities say he’s in the middle of serving a three-year parole bit for a bank robbery back in 2010 at a bank in Lancaster, Ohio. He’d only been out of the state pokey since July 19.

Apparently he was Bonnie and maybe Duboe (who will likely be slapped with accessory charges) was his Clyde. But both are facing some real hard time for their dubious Facebook fame. And that’s not called a “McStack”—it’s called a major McStake.
