Every couple has their own habits, likes and dislikes and if you're in a long-term relationship, chances are you and your partner will have your very own in-joke that makes you smile, while leaving others confused and perplexed.
Thanks to amateur film maker Chris Melberger, we can now share in a couple's adorable, if slightly weird, joke.
Chris' girlfriend, Shan, scares ridiculously easily. And, just as any other doting boyfriend would, Chris takes full advantage of her nervous disposition.
Whether he jumps out on her or simply says "boo!", Shan can't help but shriek in fear... Until one day she takes her sweet revenge.
