One night at a bar, a friend's girlfriend decided she wanted to prank him by moving his truck (Toyota Tacoma, or whatever they were called before Tacoma) in the parking lot. However, she couldn't drive it because it was a 5-speed. So of course I got "volunteered" to move the truck.... I moved it to a different spot a few rows away. As it turns out, my friend and I liked to park manual vehicles in very different ways - I usually left them in 1st or Reverse and didn't set the parking brake (assuming on level ground). My friend was used to leaving it in N and setting the parking brake.
So a few hours later, the bar was closing and we left... My friend panicked when he couldn't find his truck! His girlfriend laughed and I laughed and he realized he'd been pranked so I led him over to where I'd left the truck. He was mad, but eventually laughed also and then he jumped in and cranked the key. Just like he was used to, he didn't press on the clutch, and since I'd left the truck in 1st in jumped forward! Fortunately there was no one standing there and no vehicle there parked in front of it. But it sure would have ended badly if there was!
