This tradie is literally dumb as fuck

funny shit 07/03/2017

A video of a Scottish tradie struggling to answer a basic riddle has gone viral around the world.

The brain teaser he was given was:

When I was six, my sister was half my age. Now I'm 70 - how old's my sister?

Which is simple to work out, right? 

(if not, we'll give you a sec to figure it out)

The answer is 67 (the brother is three years older than his sister, and if he is 70 years old then she is 70-3 = 67).

But this guy......man he really couldn't compute that in his head. "35 - she's half my age!"

And it goes from bad to worse from there....watch him struggle in the video above. And try it on one of your mates and see if they fall for it too!
