Every so often, a priceless video pops up online that puts a smile on many faces. This week, we have a dad delivering a one-of-a-kind trick that you can’t help but laugh at.

The mischievous Dublin dad David Cromwell had his daughter captivated by a pen and paper stunt. But no one could predict this ending – unless your dad has done this joke before!
