The American political satirist Jon Stewart has appeared as a guest on Egypt's top

satirical TV show, which is modelled after his own programme "The Daily Show."

Stewart was brought onto the set of El Bernameg (The Programme) wearing a

black hood and introduced by presenter Bassem Youssef as a captured foreign spy.

Youssef, one of Egypt's most popular TV presenters, has been questioned by

prosecutors on accusations of blasphemy and insulting the president.

A trained heart surgeon, Youssef catapulted to fame when his video blogs

mocking politics received hundreds of thousands of hits shortly after the 2011

uprising that toppled former leader Hosni Mubarak.

It looks like he had as much fun as he usually does on his own show.
