Dave's Credibility in the Crapper

Recently, Dave from Garfield Ridge took a serious hit to his credibility when it turns out that the nuclear weapon detonated by North Korea was not, in fact, a nuclear weapon. Sources indicate that what appeared to be a giant mushroom-shaped cloud was actually play-doh. So you can see where Dave would have gotten his false impression.

Which reminds me of a riddle I once heard. What's the difference between Dave and Dan Rather? Other than the fact that Dan Rather has never threatened to turn me into a pair of boots? Dave admits when he's wrong. Also, Dave looks like Pyle from Full Metal Jacket, not an aging pear.
