VIDEO: Children react to an adult reading ridiculous and naughty words

BJ Novak is best known for his stint as a writer and actor on the US version of The Office.

With the show reaching an end in 2013 he has turned to writing children's books with no pictures and absolutely no illustrations.

However, what would normally bore children to sleep is made a whole pile of fun as the adult tasked with reading the book must read ALL the words, no matter what!

It's the rules!

It results in some serious embarrassment for the grown-up and a great degree of hilarity for the smallies.

Novak was promoting book on Irish radio this week in the run-up to Christmas.
