The only ones who can be excused for "her and I" or "her and me" are teenagers talking among themselves. It's grammatically wrong; period. But I have another related item you might want to address. How many are familiar with this gaining-in-popularity expression: This is Jim and I's new house? Sad but true

I never thought I'd find anyone else so bothered as I am by "as best he can," but you all have proved me wrong. Of course the best explanation of its incorrectness is to look at the word "best" as a superlative; I can't think of another example of an expression that uses "as......as" with the superlative form. The incorrect phrase seems to mean "the best he can" in every instance I've seen, and I think the incorrect form has simply taken hold and is now being used everywhere--much like "I could care less." Neither makes sense, most don't seem to care (at least not at THIS POINT IN TIME; AARRGGGHHH!)
