I was sending an e-mail to a friend of mine, recently, and I happened to use the term 'Mudcatting' as part of the ongoing anecdote. My spell-checker immediately sprang into action, and unceremoniously drew that yukky red squiggly line underneath the unregognised verb.

I right-clicked, and received all these 'similar' words I could use in its' stead.

Medicating
Mutating
Mulcting
Muscatine

Isn't the Chaos Theory something else, or what?
