When I saw the SAK on his keychain early in the movie I thought "THAT's gonna come in handy some day soon!" Then he tosses the keys to what's her name before he gets on the plane

If you made a spoof of the movie, the imaginary friend could be named "Spalding"

But for the life of me I can't figure out how that jet engine would still be running as it floated on the water, threatening to chop him into fishbait.
