From today's Runner's World Article:
Happy birthday, David Letterman!
Yes, the late-night funnyman/master of irony/former Indiana weather man turns 64 years young today. Which has absolutely nothing to do with running, until you remember that one night back in November 2009, Dave's Top Ten list was titled "Top Ten Thoughts That Go Through Your Mind When Running The New York City Marathon" and was presented by none other than Meb Keflezighi, who had just won the racein question.
For my money, it's one of the funniest Top Ten lists in recent memory, not least because of Meb's obvious delight and endearingly awkward delivery.
Here it is:

In honor of Mr. Letterman and his crack team of writers — and with the Boston Marathon nearly upon us — I thought it'd be fun to brainstorm our own list, titled "Top Ten Thoughts That Go Through Your Mind When Running the Boston Marathon."
I'll start:
10. "Huh. There must be something very interesting behind those trees, because some guys interrupted their race to go stare at it."
Your turn…
