I have to agree with this, and also mention that poorly chosen "challenge questions" may be viewed as security problems. I came across a (not needing serious security, i.e. not financial or similar) site recently where one of the questions was "mother's maiden name." Since that's commonly used for verification by financial companies, there was no way I was giving it to a system that would probably store it in plaintext (easier to check against) and that anyway didn't store particularly important information.
In that case I had five questions to choose from, and one of the others was "favorite band", which falls under the ice cream problem. More choices would have made me *much* less irritated by the site. Now I wish I could remember what it was to warn others off....
