A Canadian dad introduces his children to the inventions of yesterday... by asking them to guess what a phone book is.<br /><br />Evan aged 11, Gavin aged 13, Abigail aged 13, and Ayden aged 16 appear completely perplexed in this hilarious video. <br /><br />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. <br /><br />"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."
