Of all the terrible, terrible sequels I can think of - and at the moment, Blues Brothers 2000 and Bridget Jones: Edge of Reason in particular spring to mind - surely Grease 2 is the worst. Not even the fact that it gave the fledgling career of Michelle Pfeiffer its first nudge towards bug-eyed brilliance redeems it. It is such a terrible movie that watching it was referred to in the Drew Carey Show as an example of a truly pathetic way to waste one's time. The line was, I believe:
"Oh, because you're so busy sitting around watching Grease 2 in your underwear".
This is the kind of line that can have a chaos theory-esque effect on a sharehouse, and did, in fact, result in me and two of my housemates seeing a lot more of each other's skin than we had previously. But you should not let our immense and devastating loss of pride deter you. I urge you to instead share in our collective humiliation by going out right now to rent the movie and then, having done so, gather those you live with together and strip down to your bare essentials. Even if you don't enjoy the movie - and you won't - you may enjoy the experience. Maybe.
