They tricked David Cameron and workers at the International Criminal Court, but comedians Jolyon Rubinstein and Heydon Prowse were not so successful when it came to security staff at the Israeli embassy in London.
The pair attempted to get past armed police at the embassy gates by posing as building surveyors wearing high-visibility jackets and hard hats who had arrived to plan a conservatory. But their hidden cameras were spotted and the comedians were told to leave.
The prank was filmed and will be screened in the comics’ BBC Three series, The Revolution Will Be Televised, which starts on Sunday.
Mr Rubinstein, said: “The embassy was much harder to get into than all the other places we tried.”
He added that the point of the prank was “not to make light of the Israel-Palestine problem. We are drawing people’s attention to the issues.”
But embassy spokesman Yiftah Curiel failed to find the stunt amusing, criticising the comedians for targeting “a sensitive location where terrorist attacks have taken place in the past”.
He said: “Despite their no doubt honest intent to make comedy and satire, the use of BBC public funding in order to create the appearance of a security threat at the gates of the Israeli embassy, is highly inappropriate.”
But he held out an olive branch to the pair by inviting them to the next embassy Purim party, “so they can see what real dressing up is all about”.
Mr Rubinstein responded by saying: “Me and Heydon would love to go.”
The Revolution Will Be Televised will show Mr Rubinstein suprising David Cameron by asking to sign a Bullingdon Club photo album.
The comedians also succeed in putting up wanted posters for Tony Blair and George Bush at the International Criminal Court in the Hague.
The episode featuring their failed embassy incursion is scheduled to be broadcast on December 15.
