Of course it's senseless drivel... that's what makes it amusing.
I finished reading this thread on Sunday night and thought "gee, I never see anybody famous while I'm travelling." The next morning, I'm almost sound asleep in the first row of an awful AA F-100 to Albany, and I hear an unmistakable voice... I thought about the thread and thought I was hallucinating from lack of sleep.
Sure enough, it was a local writer named Lester Munson who writes for Sports Illustrated about sports and law (he's a lawyer by original trade) and appears frequently as a panelist on various TV/radio programs here in Chicago.
He was with his wife who had a tremendously large hat box, and they were probably headed to Saratoga Springs for the start of its season. Since an F-100 has only 8 F seats, they ended up in the second row of coach. I gave him a slow "hi I know you but I'm not going to bother you" nod when he walked past me, he returned the nod, and I went back to sleep.
Granted, he's not as famous as McCartney and Jackson, but the timing was just funny.
