Singing In Their Jammies! Family's YouTube Christmas Card Goes Viral

It has become a new Christmas tradition for 'fun-loving' families to dispense with the tedious graft of writing out a zillion cards to people they haven't set eyes on for 30 years and instead use the age of multi-media to create a new way of spreading festive cheer.

And here's a family who have taken the new way to its nth degree in a homemade YouTube 'Christmas card' that will either have you rolling on the floor laughing (that's a ROFL) or gnashing your teeth with irritation (that's a GYTWI – hmmm, perhaps not!).

Anyway, it's been created by American news presenter Penn Holderness and his family as their way of sharing their family's news of the past year – and it has become an internet sensation, amassing 400,000 hits and counting.

It shows Penn and his wife dressed in their 'Christmas Jammies' dancing around and singing with their young children as they tell friends and family about their new car, daughter Lola's school achievements and Penn's new job.
