The joke is on David and Victoria Beckham after they became the butt of the "funniest joke" at the Edinburgh Fringe Festival.
The winning joke came from dead-pan Canadian comedian Stewart Francis:
The Beckhams have an original taste in names, having called their four children Brooklyn, Romeo, Cruz and Harper Seven.
Each year, the TV channel Dave sponsors a competition to find the Funniest Joke of the Fringe.
A team of comedy critics narrow hundreds of suggestions down to a shortlist before 3,000 comedy fans vote on the best joke. Mr Francis' one-liner won around a fifth of the vote.
Mr Francis, whose show 'Return Of The Lumberjacks (Back by Poplar Demand)' runs until August 26th, made two appearances in the top ten.
His other winning joke was: "I saw a documentary on how ships are kept together. Riveting."
He fought off tough competition from the likes of one-liner legend Tim Vine and character comedian George Ryegold.
The top ten jokes were as follows:
1 Stewart Francis - "You know who really gives kids a bad name? Posh and Becks."
2 Tim Vine - "Last night me and my girlfriend watched three DVDs back to back. Luckily I was the one facing the telly."
3 Will Marsh - "I was raised as an only child, which really annoyed my sister."
4 Rob Beckett - "You know you're working class when your TV is bigger than your book case."
5 Chris Turner - "I'm good friends with 25 letters of the alphabet ... I don't know why."
6 Tim Vine - "I took part in the sun tanning Olympics - I just got Bronze."
7 George Ryegold - "Pornography is often frowned upon, but that's only because I'm concentrating."
8 Stewart Francis - "I saw a documentary on how ships are kept together. Riveting."
9 Lou Sanders - "I waited an hour for my starter so I complained: 'It's not rocket salad'."
10 Nish Kumar - "My mum's so pessimistic, that if there was an Olympics for pessimism ... she wouldn't fancy her chances."
