As an alternative to poor grammar and sounding like a twat, one might simply say, "I am taller than he is." Sure, it's an extra word, but it's both correct and sounds natural.

I struggle with that occasionally. Using "him" in that sentence would make me die a little inside, but I also don't want to sound like a prick.

Speaking of comparatives, a fellow grad student here at the University of Maryland is working on a phenomena called the comparative illusion, which involve sentences like the following:

More people have been to Russia than I have.

Think about that one for a bit. LL did a post on it, btw: http://itre.cis.upenn.edu/~myl/languagelog/archives/000860.h...
