Londoners stunned by Sky 1’s imaginary friend stunt.

Just because you can’t see someone’s imaginary friend, it doesn’t meant that they’re not real.

The prank was set up to promote the third series of Sky1’s award winning comedy Moone Boy, written by Chris O’Dowd, and starring the Irish funnyman as a young boy’s imaginary friend.

Matthew Arnold, Marketing Manager, Sky 1 says: “In celebrating Moone Boy’s return to Sky 1 on March 2nd, we wanted to have a bit of fun with one of the show’s central themes – the joy of having a make-believe friend.

Moone Boy is the story a young boy and his imaginary friend, so we thought this prank was the perfect way to celebrate the launch of series 3 of the show and connect the public to the life of Martin Moone and his own imaginary friend played by Chris O’Dowd.”

The brand new series of Moone Boy airs Monday 2^nd March at 9pm on Sky 1.
