In case any of you are wondering why I don't include more humour in this blog, it's because I'm a linguist.
That means I find things like this funny (thanks to the blog of Cath, a recent commenter). See also the comment thread in Cath's blog post.
If you want more of this sort of thing, you'll have to ask for it. Otherwise, I'll keep my academic sense of humour safely bottled.
