Lazy Comment Generator: Please tell me someone has done this

I was just at fairyhedgehog and someone commented that they'd like to see a "lazy commenter" generator. A real one.

I don't know how the web works, but it looks like you could create a service that uses OpenID: You enter the feeds you want to track into a form, and with each feed update, your OpenID logs in and leaves a random comment from whatever you enter into your comment file:

1. "You go, girl!"
2. "Death to The Man."
3. "LOL. Seriously, you rock!"
4. "Ask your doctor about Viagra."
5. "I did that once, I swear."
6. "I was just having that same thought. I swear we're like twins. I think I love you. So I guess we're not twins because then the love thing might be creepy."
7. "If that happens, I will move to Canada."
8. "If it weren't for the drugs, I think I'd kill (myself/you/Oprah)."
9. "I used to have that problem before I found Jesus."
10. ":)"

So I post something new, and your autocomment generator gets my feed update and automatically logs in with your OpenID and submits a random comment from the ones you entered into your account.

The only flaw I can think of is the "Captcha" or security words you need to type in to prove you're not a computer.

You may ask, what's the point? But I'd say that any comments are better than none. Yeah, rereading my examples above, on second thought, maybe not.
