I saw Die Hard 2 : Die Harder on network TV, and when they got to this line, they used “Yippie-ki-ay, Mr. Falcon!”
I had not seen the rest of the movie, and that of course made no sense. I finally saw most of the whole thing again, and it turns out that ‘Falcon’ is the call sign the bad guy uses when he hijacks the plane or something like that. It still doesn’t make much sense, but it’s interesting that they put that much thought into it.
