I phoned the radio station today. The presenter answered and said,

"Congratulations on being our first caller, all you need to do is answer the following question correctly, to win our grand prize!"

"That fantastic!" I shouted in delight.

"Feel confident?" The presenter asked, "Its a maths question."

"Well, I've got a degree in maths," I proudly replied, "and teach it my local school."

"Ok then, to win our grand prize of 2 front row seats to a Justin Beiber concert and to meet him back stage, what is 2+2?"
