WATCH Kids try to text on an old-school phone.

You know those round-dial phones you saw every day when you were young? Chances are your kids have no idea what to do with them.

Fine Bros, a comedy team on YouTube introduce a group of children, aged between 5 and 13, to an old-school telephone and their reactions to it are priceless.

The children were asked if they knew what the technology was and how to use it. It seems the alien object has these kids stumped.  All the laughter.
