Aside from the fact that it was a rerun, it was awesome. I enjoyed how they went so far as to Clay Animate the opening footage, and even the Jackass clips. (and, of course, Conan's duck and hiss!) And what better than a clay Mr. T surprise!!!! And the bloopers were surprisingly entertaining for just being a bunch of clay figures falling over/apart.
History IQ was like an automatic 'must-watch' show for me. It took a bit to get used to Marc Summers as a serious game show host (if you've ever seen him hugged by slime-covered contestants on Double Dare, you'd understand my difficulty too)
