The Big Bang Theory cast send lovely message to Dublin boy with cancer

The parents of a four-year-old who was diagnosed with a rare brain tumour last year have said they are "crying with happiness" after the cast of The Big Bang Theory sent their son a special message.

Four-year-old Oscar Keogh was diagnosed with the rare brain tumour called Diffuse Intrinsic Pontine Glioma, which cannot be treated or operated on, in January last year.
