A co-worker of mine sent an email with this question to the whole "dev" group:

"Does anyone have a random password generator that I can quickly plug into my application?"

My response:

"Guid.NewGuid().ToString()"  :P

What's even funnier is that my team lead sent the exact same response (Guid).  Others replied with "google '.net random password generator'".  LOL.

The correct answer turned out to be:

System.Web.Security.Membership.GeneratePassword

But of course that's not nearly as funny, now is it...
