Update: by way of comments, I'm pointed at LibDems4Cameron.co.uk which is much better, and rather amusing:
Ten reasons to vote for us (because we can count past six)
Update 2: Given the large number of referrals I'm getting from a private LibDem forum, I'm guessing someone has read this. Given that most of the problems have been fixed in a rather inelegant way, I'm guessing someone listened to my request. As pointed out in the comments, it would be much better to reformat the page so it's actually a proper page rather than text in a .jpg, dial-up users (like me) would like it as well. Still, the humour is good if nothing else.
