Boy, 4, scared by surprise party

An amusing video has emerged of a boy running away as he enters a surprise party.

The footage, shot in Winslow Township, NJ, USA, shows four-year-old screaming and running out of the house as he arrives at the surprise party organised for his father.

"My husband opens up the door to a huge surprise party being thrown for him yet my 4 year old son steals the show," the mother wrote online.

"He gets spooked and runs faster than an Olympic track athlete."
