Brainteaser Tie

Brian's tie tonight, a black and white stripe, reminds me of those brainteaser puzzles that teachers and psychology professors show you of the two lines that look like this:

<-------->
>--------<

The instructor then asks you, "Which line looks longer to you?" And, of course, you answer that the line with the outward arrowheads looks the longer of the two, and you are wrong! because the lines are actually the same; it's a perception thing. Well, Brian's tie tonight has that whole business going on: the black stripes and the white stripes just might be the same width, but who can really be sure? The white ones look like they might be narrower, but it's awfully hard to tell. Besides, it's just a tie, and really, no one's paying me to do this.
