I found this by accident when searching for a command in `M-x`. It is really a nice lorem-ipsum generator but it adds some "subversive" words (as described in the manual), so was quite afraid to use it in public/team projects to avoid "unnecessary attention" :D.
I found compose-email by accident when I accidentally typed C-X M (probably meant to ESC-X msomethingsomething). 95% of my init.el is disabling crap and re-binding keys to #'ignore.
