Big Brother plays prank on Sam and Amanda

Big Brother's party for the twins turned into a nightmare as the food contained nasty surprises.

The housemates gathered around a window which allowed them to see an array of cakes, pastries, ice creams and sweets in a separate room, decorated with pink birthday balloons and streamers.

"Oh my God!" screamed Sam, as Big Brother asked her, Amanda, Nicky and Liam to go into the "party room".

The group entered the room while the rest of the starved housemates looked on through the bedroom window with jealousy. As the housemates picked through the food, Amanda yelled: "Slop, it's all slop!"

Amanda discovered that beneath the thin layers of cream, pastry and icing, the birthday treats were filled with the same slop they had been eating since they failed their insomnia task.

"That's horrible. What a shit party the wankers," cried Liam.

Liam, however, managed to focus on the bright side as he cut in the birthday cake to reveal corned beef: "I like corned beef," he said to the girls.

The group searched through all the treats on the table in an attempt to find something edible. Much to their disappointment, they found slop mixed with everything, a whole fish hidden in the truffle and curry powder over all the sweets.

Nicky lost her temper, referring to Big Brother as "fucking bastards" and said to the twins: "I can't believe they didn't give you a proper birthday."
