A long time ago while working on a *nix box logged in as root, I executed a simple "!find". Basically execute the last find. In root's history, the last find command was something like "find ... -exec rm ...". The command was run at the root of the content directory of a CMS, deleting all the content (major media website). CMS was down while backups were restored. I now never execute ! commands as root. Actually, nowadays I simply use CTRL-r.
