If they transplanted the "I ran out of bullets" line into the unrated cut of Live Free or Die Hard, I'd be perfectly satisfied with it.
there are two lines from the PG-13 cut that are actually better than their unrated equivalent. That's one of them, and the other is the replacement of "[I'll] get my daughter back, kill those motherfuckers" with [I'll] get my daughter back, kill everybody else" - there's just something about the delivery of "everybody else" that's hilarious in terms of implying that he knows there are no bystanders around, and that, being an action hero, he can happily kill... everybody there.
There needs to be a definitive cut with those two lines back in, and the rest of the profanity kept in.
Yippee Ki Yay, Monday to Friday.
