How about the joke about a guy who manages to conjure up a genie. The genie agrees to grant him one wish.
The man points to a map of the Middle East.
‘Okay … how about peace in the Middle East?’
‘Sorry … I have my limits, I’m a genie, not God.’
‘Okay … can you make me irresistible to women?’
The genie hesitates, then says, ’Let’s have a look at that map again.’
