Let's be honest here, the stoner demographic isn't exactly the brightest lot. Despite ganja advocates claiming pot gives you superhuman abilities, the evidence suggesting otherwise continues mounting.

Take this latest development for instance. A mop-topped skeevy weed-puffer got busted trying to pay for his McDonald's with some Mary Jane. I kid you not:

Anthony Gallagher, 23, was busted early Sunday morning after he tried to barter with a fast food employee at the Port St. Lucie drive thru: greasy food for some weed. Police said the McDonald’s employee turned down Gallagher’s pot payment around 2 a.m., then called 911. Gallagher allegedly left the drive thru, then circled back shortly after, when officers were already waiting for him. Port. St. Lucie police said officers smelled a “heavy odor of marijuana emitting from the car” and found 11 grams of weed. Gallagher admitted to trying to pay with marijuana, but said it was all in jest. He was arrested for possession of marijuana and driving under the influence and booked at the St. Lucie County jail.

"Heeeeey man, like I'm a lil' short on dead presidents. I mean, like, I've got some green on me, but not that kind. I'll tell you what, muchacho. How's about I trade you some of this sticky for that Quarter Pounder there. Wait, you're calling the bacon boys? Way to harsh my mellow, bruh."

Only a spaced-out stoner dingus would think illegal substances could pass as legal tender. This is what happens kiddos when you put down the books and pick up the reefer pipe. Copious amounts of dumbassery. Maybe next time, when Smokey McPots here gets the munchies, he'll use normal currency to score his McNuggets.

Look, don't get me wrong, I'm all in favor of you being able to toke up without fear of a prison sentence. Though, I think we can all admit the cannabis doesn't exactly work wonders for your noodle.

Speaking of that:
