Mujibur and Sirajul

Mujibur Rahman and Sirajul Islam are businessmen in New York City who are known for numerous guest appearances on the Late Show with David Letterman.

Natives of Bangladesh, each man immigrated to New York and became employed at souvenir shop K&L's Rock America, near the Ed Sullivan Theater, where The Late Show was produced. David Letterman did frequent comedy spots featuring the salesmen, and in 1994, he sent them across the country as roving correspondents for the show. The team toured many U.S. towns and cities, and the duo were greeted as celebrities. Sirajul, for example, threw the opening pitch in a home game for the Sioux City Explorers. The duo were also sent to Super Bowl XXIX to tape spots for The Late Show.

Mujibur and Sirajul guest-starred as themselves in a Cartoon Network/Adult Swim show Space Ghost Coast to Coast, when they realized at the end, they got pizza for Space Ghost, Zorak, and Moltar and they laughed at a "piece of" joke.

In 2003, when K&L's Rock America closed due to an increase in rent, Letterman told the duo he would miss them, and he gave them each a dozen roses and a new vacuum cleaner as "parting gifts."
