My invitation to provide a caption for the strangely compelling photo of the aftermath of the Woodley Park Metro pileup prompted entries from hundreds of readers.

Most of the entries fell along the same lines, emphasizing either the reproductory nature of the photo or its inherent "Ozness."

I've included some of my favorites. If I didn't print yours, it's probably because another person had the same idea sooner or phrased it in a slightly more pleasing way. Here they are, in no particular order:

"On the bright side, we do get to pocket another 70 cents from the fare reduction."

-- Eric Martin, Laurel

"Uh-oh. Better call Maaco!"

-- Carrick Herbert, Alexandria

Drumroll Please (Then Eggroll)

And now for the lunch-winning entry. I chose the entry from Peter Lagiovane of Chambersburg, Pa., because it was so dissimilar from the other entries. And in its way it paid homage to a native Washingtonian. Peter's caption:

Metro riders line up to view Duke Ellington's famous "A-ieeee! Train."

Women and Children Second

When she heard that Metro had redesigned its Web site, www.wmata.com, Adrienne Flave thought she'd take a look. But in the section "How to Travel," she found an example of blatant favoritism. Under the heading "Riding Metro" is this instruction: "Stand clear the train car doors and let writers get off before you board." When she pointed this out to me, Adrienne wrote: "You're lucky that your profession is singled out for courtesy by Metro. I, a government analyst, will have to fight my way through the throngs to disembark!"
