Ok, my favorite word-processorized boo-boo. For reasons that are now lost in
history, my company is called 'WordMongers' [we sell words, right, geddit?]. In
negotiating a contract a few years back on behalf of the company, I requested
that all instances of the term 'author' be changed to 'WordMongers', as the
contract was on behalf of the company.
The signature field came back 'Duly WordMongersised:'. No-one noticed except
me, so it went into history like that, as I rather liked it.
