All right, you lot are smart, but I reckon the over/under before someone screws this up must be about 29. (Some day I shall try it on a more public message board and will be delighted if it gets to 13.)
What I would like to see, if you would be so kind, is a single thread of comments. The first reply should be the number one, the second reply should be the number two and so forth. Any number exactly divisible by 3 is replaced by "Fizz", any number exactly divisible by 5 is replaced by "Buzz" and any number exactly divisible by both is replaced by "Fizz Buzz".
The count stops when:
someone posts incorrectly,
someone doesn't post as a response to the most recently-posted comment,
someone posts to the thread a second time,
someone gets geeky and decides that we aren't playing in decimal,
someone gets bored or drunk and instead of a number posts something else like a rude word, an advert for recreational medicine, a program to automatically generate the correct answers or an argument that my rules are wrong and 4725 should really be Fizz Fizz Fizz Buzz Buzz Grooby,
someone cocks up in some other more creative fashion that I haven't foreseen
someone tries to edit or delete their reply once they've spotted their mistake and realised they've stopped the count for everyone. (Don't forget, I get the replies e-mailed to me.)
I have faith in you. Go and set a world record that will never be broken.
