Sarcastically comment on someone who insulted Dr. Paul Krugman and expressed doubt in their intellectual abilities.
Gosh, you're awesome, in a way. When you win a Nobel prize we'll all be sorry we laughed at you! Yessiree, calling Doctor Paul Krugman a "dumbass" sure puts him in his place. Only an awesome intellect like yours could put Doctor Paul Krugman in his place. I'm laughing now, but I won't be laughing when you publish your magnum opus. That's for sure.
