Was recently encoding my Stargate: SG-1 DVDs to move them to plex. I was encoding it on a system other than what was serving it, so I had to copy it. It's surprisingly difficult to "scp" a file with a colon in it directly.

I also love when you're using bash and you have a file with ! in the name, and you accidentally fail to correctly backslash it, you not only get "bash: !rest_of_filename: event not found", but it also fails to add that command line to the history, so you can't just hit up and fix it. You have to actually go to the mouse and copy and paste.
