This isn't exactly a random sample, it's from okcupid. I don't know all that much about okcupid but it seems like the sort of place where people who think they're special would congregate.

americans are the ones mixing up "its" and "it's", "their" and "they're" etc - and we're talking about supposedly educated people here.
somebody mixing up basic grammar in their native language after being exposed to it for 20, 30 years doesn't make me laugh, it is incomprehensible to me.
