Okay, story time. So a friend of mine is a tram driver. He fondly recalls the time when some idiot had parked across the tram line to go inside a store. Much use of the horn got said idiot out, but he didn't see the problem; "Why don't you just drive around me?" he shouted. My friend shouted back "Why don't you come up here and try that?" The idiot actually came up, sat down in the tram driver's seat, and then promptly deflated as he realised there is no steering wheel, a tram runs on tracks. He got up, with a very long face, and left to move his car to the tune of laughter from passengers and bystanders.
