Report from Week 275,

in which you were asked to come up with limericks about someone who lives in the Washington area. One note: You showed yourselves to be clever and inventive, but not very lyrical. Your poems required substantial editing for rhyme and meter. We would conclude that you have "tin ears," but that would be unfair to tin, a perfectly nice substance. No, your ears are more like "phlegm-ears," or "Vaseline-and-catsup-ears," or "that-membrane-that-covers-your-dog's-eyeball-when-he-is-asleep-ears. " Anyway, grading limericks is tough. When points are awarded for degree of difficulty, as they must be, some of the worst poems ever crafted can ooze their way into print, such as this ghastly mess by Elden Carnahan of Laurel:

A yuppie who lived in Annapolis / Drank Evian to keep himself Snapple-less. / He wore Birkenstock hose, / And his sound system (Bose) / Played jazz, not John Tesh or that crap o' Liszt.

+ Third Runner-Up:

There once was a dancer from Towson,

Who shimmied without any blowson.

Removing her raiment

Brought annual payment

Of sixty or seventy thowson.

(David Smith, Berkeley, Calif.)

+ Second Runner-Up:

Two Amish lads from McLean

Had ambitions to deal in cocaine,

They'd no cartel, just cart

But their "cover" was smart.

Now they're millionaires, simple and plain.

(Howard Walderman, Columbia)

+ First Runner-Up:

Ben, who was wanted in Cheverly,

Evaded the cops rather cleverly.

With the dragnet convergin'

He consulted a surgeon,

Now he's living in Fairfax as Beverly.

(Dave Zarrow, Herndon)

+ And the winner of the

"Running for President" game:

An addled old dame from Ward 3

Tells her chauffeur, "To Raleigh's, Henri --

Then Garfinckel's next,

And Lansburgh's, and Peck's,

And Woodies on F Street for tea."

(Courtney Knauth, Washington)

+ Honorable Mentions:

There once was a man from Manassas,

Who wed the most vengeful of lasses.

You remember his name

For, though fleeting is fame,

Notoriety's what never passes.

(David Smith, Berkeley, Calif.)

An impotent man out in Crofton,

Desired his sex much more often.

"Pay up, HMO ..."

The insurer said no,

Its firm stance on Viagra won't soften.

(Dave Zarrow, Herndon)

There once was a girl from Chantilly

Who was fiercely pursued by Slick Willie,

Said she with a sigh,

I'm not lord of your fly

I'm as pure as Milli Vanilli.

(Howard Walderman, Columbia)

William, of Capitol Heights,

Is a minister, daytime and nights.

Without hesitation

His small congregation

Dubbed him D.C.'s Bill of Rites.

(Mae Scanlan, Washington)

A doyenne from Takoma Park

Returning one evening at dark,

Decided to take

A jaunt by the lake,

And encountered a ma'am-eating shark.

(Mary Jane Mitchell, Ellicott City)

A hostess of note from McLean,

Treated the help with disdain.

Till, at one of her "do's"

She noticed the booze

Was too yellow by far for champagne.

(Jennifer Hart, Arlington)

A Warrenton lass named McKinnon,

Met a horseman who had a big grin on.

"What county is this?"

He asked, stealing a kiss.

She said, "Fauquier, and the horse you rode

in on."

(Dave Zarrow, Herndon)

A sick gal from near Tysons Corner,

Had insurance that made her forlorner.

Despite fever and chills,

It rejected her bills,

All of her friends now must mourn her.

(Joseph B. Pincus, Springfield)

There was a young lady from Cheltenham

Who bought some new pants and looked sveltenham,

If a little bit red.

When asked why, she said,

"It's because of how tightly I'm beltenham."

(David Smith, Berkeley, Calif.)
