Watch these Canadian kids try and guess what a phone book is

A Canadian dad introduces his children to the inventions of yesterday... by asking them to guess what a phone book is.

Evan aged 11, Gavin aged 13, Abigail aged 13, and Ayden aged 16 appear completely perplexed in this hilarious video.

Barry, their dad, told Newsflare: "I realized when I was my children’s age the phone book used to be so important, but hasn’t been anything I’ve used in years.

"It got me thinking that my kids probably don’t even know what it is and it would be funny to see what they came up with."
