Rangers Fan Given Trick Birthday Cake Made with Celtic-Coloured Sponge

A Rangers fan received an unwanted surprise on his birthday when he was presented with a cake adorned with his team's badge and colours...but made with Celtic-coloured sponge.

An amusing video posted on the Facebook page of cake-makers "Cupcakes by Lilian" shows the moment birthday boy Iain Orr cut into cake...to reveal the green and white of arch-rivals Celtic.

The pranked Gers fan eventually realised he'd been had, much to the amusement of his surrounding friends.

"It was hilarious—totally unexpected," Mr Orr told the Scottish Sun (via the Telegraph) later.
