Well, aside from the fact that the redhead in question was an incredibly hot redhead (redheads start at 3 on the 1-10 scale) everyone knows that a man should choose that which is attainable over that which produces enough drama to cause misery.
Now don't get me wrong, Denise Richards is hot (see the classic
Undercover Brother for more information.) I'm just saying that she put Casper van Diem's character through the emotional roller coaster, and he should've told her to hit the road.
Of course, none of what I just wrote proves anything except clarifies my own thoughts and theories, and provides proof that I will never be a Hollywood screenwriter.
