What is my girlfriend's husband suddenly doing here?

Anyone who's seen the videoBanged my friend's husband knows who I'm talking about... I was just in the shower when I got a call from HIM. He said: I'll be with you in 2 minutes, it's very important! Without me even being able to say a word, he hung up again. So I quickly hopped out of the shower, just managed to dry myself off and the doorbell rang. I put a towel round my hips and greeted the gentleman nicely... But what does he want that is so important that he has to take me by surprise like that? Well, let's see :-)
