Google chooses them; I don't. Just like when some weird righist ad appears on a lefty blog. If you choose to click through the advertiser, and buy what they're selling, that's your business. Caveat emptor, and all that. But unless I specifically endorse it (Feather razor products, why not advertise on my blog?) I don't vouch for it.
