The Simpsons pay tribute to David Letterman

The Simpsons have paid tribute to US talk show host David Letterman, who announced he will retire from his programme next year.

The one minute clip shows Homer and his family overcoming a security guard and traffic jam as they make their way to the 'Late Show with David Letterman'.

The sequence then ends with Letterman's longtime bandleader Paul Shaffer conducting a version of The Simpsons theme tune.

Letterman, 66, who began hosting the show in 1993, said he will step down in 2015 which led to tributes from celebrities and US President Barack Obama.
