Take a lesson from the Far Side 'What we say to our dog' cartoon.
If person = twit then change every word that isn't in('the','it','and','your', 'our',or whatever ) to 'blah'. Observing capitalisation.
So my first sentence could well be "Blah a blah blah the Blah Blah 'blah blah blah to our blah' blah."
Hmm... I'm going to muck about with sed/awk this afternoon if I have time :)
So at least if you do see an LRPD from a twit, at least you might be mildly entertainted.
This, of course, opens up the possibily for Swedish Chef, Jive, Valley Girl and other filters. Oh well, can't have everything.
