Police in Uganda have uncovered a the best part of any convent’s garden – the acre of marijuana.

According to the BBC, two nuns and two porters at the convent have been questioned, with local media reporting that one of the nuns claims the illicit crop was used to treat the pigs and other animals raised at the convent. Which is pretty much the oldest scam in the book.

“Oh, wow, officer, I didn’t even realize that was pot. I just use it to treat my pig’s…porcine…glaucoma…and such.”

Sure it sounds like a good story when it’s coming out of your mouth, but that tired old line has never worked for anyone, short of divine intervention of some…

Oh, I see what you did there.
