When I was new with SSH and everything, I managed to enter vim on my session on a server I was managing. Didn't manage to exit. So quit the SSH session and logged back in, still in vim, what to do? Well, I logged in as another user and rebooted the server. Not my proudest moment.
Back at my first job, since it was a fairly infrequent occurrence, I would occasionally ask my boss how to get out of vim. He would laugh and enter some new convoluted command every time!
It's like getting your head stuffed into a toilet bowl at a boys' boarding school. Afterwards, you feel like part of the gang.
