One of mine was when I was camping and we were walking with some Canadian tourists and for some reason we started making jokes about wolf creek and telling them we have a serial killer problem... When we were reaching the beginning of the track we noticed search and rescue, police, detectives and ambulances and I thought it would be funny to say something about it's probably got something to do with that serial killer they never found, we were laughing but the Canadians were getting a bit nervous.... Next thing we know the police start asking every hiker that walks past about why we were there and if we saw anything..... Turns out there was a serial killer... they found three tourists tied to trees, two of them were dead, a km or two away and they just caught him and wanted to know if anyone saw anything..... I was so scared I was going to jail after making those jokes and feel like a piece of shit till this day because I probably scared those guys for life
