The RCMP Officer And The Motorcycle Rider
An Royal Canadian Mounted Police officer stopped to help a stranded motorcycle rider standing beside a stalled motorcycle in the mountains. It was extremely cold, and the rider was heavily dressed in a helmet, balaclava and snowmobile suit. In a muffled voice, the rider told the Mountie that the carburetor was frozen.
"Well, pee on it," the Mountie said.
"Can't," replied the rider.
The helpful Mountie unzipped his fly and proceed to pee on the carburetor himself, and the bike soon fired up.
A few days later, the local department received a thank you note from a father, grateful for the roadside assistance his young daughter had received from the RCMP.
