A son has seemingly spent a lot of time scaring the bollox out of his poor dad - video taping his reactions before collating them into this minute and a half long video.
Half-way through the compilation the tormented father looks like he's about to crumble, he never loses it, but instead continues to just yelp away like a confused dog - just about managing to throw in the odd 'Fuck' to remind us that he's a real person.
Caroline Wozniacki seems to get the best reaction out of the scared dad.
