David Walliams horrified as Simon Cowell tricks him into handing over £1,000 cash when he loses hilarious Britain’s Got More Talent challenge

DAVID Walliams was left horrified after Simon Cowell tricked him into handing over £1,000 cash.
It all happened when the comedian, 47, lost out on a hilarious Britain’s Got More Talent prank.

The challenge involved not being able to say the “number 17” – if you said this number you lost.

First of all Britain’s Got More Talent host Stephen Mulhern played the prank on Simon, which saw him ask Simon the answer to a number of sums, without saying 17.

The last sum was “what is 10 minus three?” – to which Simon replied “seven”.

Stephen then quickly replied, “Thanking you!” – to signal that Simon lost the joke, which of course he hadn’t, so Simon said, “But you said 17!” – which was in fact the joke, as Stephen had got him to say 17. Keeping up? Good.

Simon loved the joke so much he wanted to play it on David – and even bet him £1,000 that he would lose.

However, the prank did not go down too well with Mr Walliams, who looked less than impressed when he fell for the joke.

Simon couldn’t contain his excitement at making David look stupid, and jumped up in the air shouting: “You owe me a grand!”

To which David replied: “I haven’t got in on me, but I’ll give it you, cause you need more money don’t you!”

The show was a tease to get fans excited about the return of Britain’s Got Talent tonight.

The show will also see Ant McPartlin’s big TV comeback.
