Smart Idiot

Note that this will never happen in real life.

When some Dumbass's IQ increases by tenfold. Or maybe even one-hundredfold. The Dumbass apparently has a break of intelligence and shows their hidden mental capabilities. However, this break is rarely ever long-lived and might only be played for a gag. The Dumbass suddenly becoming the Genius for about ten seconds will amaze those around them and is supposed to make the audience laugh because it goes against their expectations for that person.
