Gym Shorts

Two guys were walking down the street one day when they came across a small pair of gym shorts on the ground. They decided to put a sign up on the church bulletin board so the rightful owner could claim them.
The first one starts to write out the sign, "FOUND: one pair of boys gym shorts..."
"Hold on," says the second, "Those are girls gym shorts."
"No they're not," says the first, "They're boys shorts!"
The second grabs them from him and takes a closer look, "No, no ... Definitely girls gym shorts!"
The two of them are inspecting the shorts in turns and arguing.
"Boys shorts!", "No, girls shorts!", "Definitely boys shorts!" .... and so on.
The local priest is walking past as the two men argue and can't help but ask them what the commotion is all about.
The first guy tells the priest, and asks him if he could sort out the argument.
The priest takes the shorts, has a good long sniff, and after pondering for a few moments he looks at the two men and says: "Definitely boys shorts!..... .... but not from my parish!"
