Mujibur Rahman and Sirajul Islam are businessmen in New York City known for numerous guest appearances on the Late Show with David Letterman.
Natives of Bangladesh, each 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.
Sirajul threw the opening pitch in a home game for the Sioux City Explorers.
In 2003, when K&L's Rock America closed due to an increase in rent, Letterman told the duo he would miss them, and gave them each a dozen roses and a new vacuum cleaner as parting gifts.
