A friend of mine fixed my TeX setup yesterday (thanks), in order to get rid of prancing letters in the PDF version of my Bachelor’s Thesis. There was a point when he told me that my Linux is broken, when I had a look onto the screen in order to find out what he was talking about, I saw the following:

marcus@mobilHal:~: vi
-bash: vi: command not found
marcus@mobilHal:~: vim
-bash: vim: command not found


Still laughing about that
