#3: Beware of Cougars
This sign warns hikers of “cougars in the area,” but the humor comes from the double meaning. Alongside the usual advice to stay on trails and travel in groups, it adds a cheeky warning: men under 30 should not travel alone, playing on the slang for older women dating younger men.

The joke works perfectly because it’s disguised as a standard wildlife warning. Drivers or walkers might expect an actual mountain lion, only to realize it’s also a playful jab at human “predators.” It’s a funny reminder that not all dangers in the wild have four legs.
