Mike Huckabee
Does anybody else remember Mercer fooling Mike Huckabee while he was still Governor of Arkansas? It was during the joke about Canada building a protective dome around its 'national igloo' - which was said to be an exact replica of the American capital building - in order to protect it from global warming. It seems interesting that Huckabee was so easily fooled by such an absurd joke. Or perhaps he was just playing along...
Either way, pretty amusing considering his current situation.
