No matter how wacky the idea is, you can usually find a handful of cranks with Ph.D.s to back you up!
The corrections I'd make is that it's not "usually," it's "always, if the idea is well-known" and that the Ph.D.'s will even be in the academic field that's most relevant to the crank theory. I'm sure someone could create an equation that as a theory approaches pure wackiness, the number of Ph.D. holders willing to support the theory approaches but never reaches zero.
I used to think that creationism is the one exception, but I've since heard of one or two people with biology Ph.D.s from real universities, not the fake religious ones, that will openly advocate it.
Global warming skeptics hate to be compared to creationists (except for the ones who are also creationists, like Roy Spencer), but having a few experts in a field back an idea rejected by the broad consensus doesn't give the idea much credibility.
