Typo/Misspelling Wordpress Plugin

I searched the forums (and everywhere else) and I cant find a plugin that will generate typos and misspellings from keywords in a wordpress post or title. No typo/misspelling plugins period actually, from what I can find I have done well with typos and would love to have something like this for my autoblogs. Has anyone ever seen any form of a typo/misspelling plugin for wordpress?

Thanks in advance!
