I realize this thread is taking an abrupt turn, but hey, it's in the pub...
I've had some bad hangovers, but I don't think one's ever gone grammarial.
There are situations in which a split infinitive sounds perfectly fine to me, and others in which it just sounds wrong, and I don't even think there's rhyme or reason to it. I guess I'm just a snooty priss. (Another word for which overly pedantic lexicographers would hang me out to dry!)
"To seek out new life and new civilizations, to boldly split infinitives that have never been split before..."
