Once - long, long ago - a major news event would occur and there'd be the usual comment of "... and I wonder how long it'll be before we start hearing the jokes about it?"

Now, thanks to twitter, you can be sick of the jokes before you've ever really digested the news.

It's less than 45 minutes since Liam Fox jumped, and I'm already thinking that if I hear one more comment about him having dropped his resignation letter in a bin in St James' Park I'll have to murder someone.
