Smart Idiot

''They're sucking on their own toes one moment, then the next, they're going off about the secrets of the universe. Then the moment after that, toe suckin' time.''

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.

Even though Smart Dumbass is mostly played just for a quick laugh, there are occasions when the Dumbass stays smart for a meaningful amount of time. These occasions are When Dumb Gets Smart. In times like these, the Dumbass becomes the Smart One either because they've recently realized their own moronic ways and understandably gets tired of them or they get into some Terrible Accident, such as a hard hit to the head, that grants them intelligence. At first, they're delighted to have a functioning brain for once, but as time goes on, Good Things Get Crappy and those around them can't stand being around somebody with superior intelligence, then keep away from the new Smart One. They then see how lonely it is to be smart and revert to their dumb ways using whatever methods they have available.
