Egyptian-American comic Ronnie Khalil has just headlined the first major stand-up comedy show in Cairo since the Egyptian revolution.Local comedians joined him on stage at the gigs, which were delivered half in Arabic, half in English.The satirist told the BBC World Service that taboos on what you can and cannot say remain, but that did not stop him poking fun at "everyone", including the country’s ruling military."Egyptians are very well known around the region as having a great sense of humour," he said.
