One-liner specialists Stewart Francis and Tim Vine each make two appearances in

Canadian comedian Stewart Francis picked up the Dave award for a joke lampooning the Beckhams' choices of children's names.

Take a seat and brace yourself – here is the funniest joke from this year's Edinburgh festival fringe, courtesy of comedian Stewart Francis: "You know who really gives kids a bad name? Posh and Becks."
Of course, comedy is subjective, so if that didn't have your sides splitting, try out the gag judged the second funniest this year, from Tim Vine: "Last night, me and my girlfriend watched three DVDs back to back. Luckily, I was the one facing the telly."

The two gags top a poll at the fringe now in its fifth year. Francis, the Canadian one-liner comic, picked up 20% of the votes to win the fifth annual Dave award for the funniest joke of the fringe. About 3,000 people voted for the joke, choosing from 30 which had been gathered by a panel of comedy critics and writers.
It was one of two jokes from Francis, a frequent panellist on BBC2's Mock the Week, who also came eighth with: "I saw a documentary on how ships are kept together. Riveting!"

Francis said of his win: "1969 West Mall Soccer Association's Most Valuable Player, and now this … thank you, Dave."

The joke is taken from his show at the Assembly Rooms, called Return of the Lumberjacks, in which he is reunited with fellow Canadian comics Craig Campbell and Glenn Wool, 15 years after they made their Edinburgh debut together.

Vine – who was also runner-up last year but won in 2010 for his line "I've just been on a once-in-a-lifetime holiday. I'll tell you what, never again" – also came sixth this year for "I took part in the sun-tanning Olympics – I just got bronze."

Previous winners of the award include Zoe Lyons in its inaugural year with an Amy Winehouse joke, Dan Antopolski in 2009 for "Hedgehogs. Why can't they just share the hedge?" and last year's winner Nick Helm for "I needed a password eight characters long so I picked Snow White and the Seven Dwarves."
