It's been a week of bad jokes - most notably Nick Clegg's "to make blue go green you have to add yellow" (who writes this guy's stuff?! Sign that kid up!) and David Cameron's attempts at humour on The Late Show With David Letterman (which were never going to be as funny as him not knowing what 'Magna Carta' meant).

But not on Twitter, of course - where there have been marvellous cracks about both Cameron and Clegg, as well as Abu Hamza, John Terry and so much more. Such as: spilling red wine on your child's schoolbook. And Bob Marley's thoughts on doughnuts. And the Mona Lisa.

But don't just take our word for it - click through this week's round-up of tweets that made us giggle, smile and loloutloud. And let us all remember the wise words of the late Tony Hancock: "Does Magna Carta mean nothing to you? Did she die in vain?"
