He has swapped numbers between hundreds of couples, helped organize more than 70 real dates and at least 19 of his romances have lasted more than a year.

This Thursday, Ibrahim will be decking his yellow cab with red and white hearts and roses in the hope of matching up yet more Mr. and Mrs. Rights.

"I've organized so many dates, and it really makes me feel good about it. I've not had one complaint," Ibrahim, 53, said.

"It's really fun. Driving a taxi in New York is not an easy job so I just try to create some fun."

"I'm looking for a low-maintenance female who doesn't enjoy the finer things in life," he joked Thursday outside the Fox studio gate in Century City.

The writer for NBC's "My Name is Earl" was joined by about 50 other people for the impromptu event dubbed "Singles' Strike."

Charles Heit, a writer for the Sci Fi Channel's "Painkiller Jane," said he was dreading picket duty until he met Cara Delizia, a petite actress. Then it didn't seem so bad.

The two planned to go to dinner and a movie after putting down their picket signs.

"It's all about solidarity, right?" Delizia said.

There have been major changes in the rankings this year. The winner: San Francisco, up from fourth place. It ranked first for culture and received high marks for number of singles, nightlife, online dating and cool. The "city that never sleeps," New York, N.Y., came in a strong second place, thanks to its performance as the country's No. 1 spot for nightlife. Entertainment mecca Los Angeles came in third, Atlanta fourth and Chicago fifth. Rounding out the top 10 are Washington D.C., San Diego, Seattle, Dallas-Fort Worth and Philadelphia.

Denver, meanwhile, our top-ranked city from 2004 to 2006, has dropped to 16th place. But before Denver city elders start beating themselves up over this, we should note that this is largely because, amid several refinements to our methodology this year, we've switched to a new way of defining each city. In the past, the boundaries and population of each city were drawn from the U.S. Census Bureau's list of "Metropolitan Statistical Areas." But in 2007, we've begun using the Census Bureau's "Urbanized Area," which provides a tighter focus on cities themselves.
