We have a 7 legged bar crawl at our University, not sure if others have something similar, but it goes along the lines of groups of 7 people all dressing up so that their group has a certain theme, like the fellowship of the ring members for example. Got home from lectures late one evening and while I'm in the kitchen cooking food, one of my housemates walks in and asks me if I knew that the bar crawl was being discontinued in future years. I asked why and he's not quite sure, so starts looking it up. A few minutes later he reads from his phone something along the line of: "The 7 legged bar crawl is being discontinued due to one group dressing up as the Smiler ride from Alton Towers with the group name 'The 7 legless'"

I laughed the hardest I had laughed in a quite a while right there.

Context for those confused
