Not sure what's the funniest part of this clip -- you decide ...
Was it Charles' surprise admission? Was it Charles chuckling "that was good" over and over again? Was it Charles snidely correcting Kenny by saying "no ... I can read?" Or was it during Ernie's intro, when he asked (rhetorically) if anyone had seen "Anchorman" and Chuck rebuffed him by saying "nope"?
I'll let you decide.
