Jack is hired to play a corpse in a terrorist drill: i.e: laying still, and not saying anything. Jack immediately fails at playing dead as he breaks into long rants about Betty's new boyfriend, Chris (who, coincidentally enough, is the counter-terrorist that hired Jack in the first place).
So instead of doing his job properly, Jack enlists Leo's aid to dig up dirt on Chris. But before Jack can underhandedly nix Betty's new squeeze, Jack's picked up by Agent Brody, who mistakes Jack for a fellow agent. He explains to Jack that mad cow disease has mutated into "smart cow", and it'll be the end of the world as we know it. Stuck in Brody's psychotic mission, Jack is dramatically dragged to... The County Fair!
