There's nothing like a good old speling misstake to make me smile. Its something most of us do, knowingly otherwise. Native English speakers from UK, US and NZ are just as likly to make mistakes as people, say, from China. But the funniest typo I came accross on flickr came from their. (How many mistakes did you spot in those three sentences?)

Anyone fancy Dried-cock Pork?
