Coupon for Craziness is the second half of the 24th episode in season 2 of Dexter's Laboratory, which first aired on January 28, 1998. In this episode, Dexter swaps places with a hyperactive boy named Dextor, who turns out to be a male counterpart to Dee Dee. After Dexter realizes how boring Dextor's parents are, he schemes to return to his own family.
Dexter is at a supermarket with his family on a shopping trip. Dee Dee, Dad, and Mom look for coupons corresponding to their favorite items. Dexter goes over to the magazine rack and reads a science magazine. Meanwhile, a boy goes over to Dexter and picks up a comic.
After the shopping trip, Dexter gets in Dextor's family's car while Dextor gets in Dexter's family's car. At Dextor's house, Dexter runs around yelling out that he was kidnapped. After a warning from Dextor's parents, Dexter feels like he's in love with the parents. Dexter practices his typing and breaks his finger.
Later, Dexter gets fed up with the "new" parents being really boring and goes back to his family. He leaves a trail of cookies back to Dextor's family, and Dexter enjoys the coupon game with his family.
The title card's coupon says that it is redeemable at Hanna-Barbera.
The magazine Dexter reads at the super market is called "Popular MAD Science" with a unique text on the word "MAD", a possible reference to MAD Magazine.
When Dextor's picture is seen inside his house his feet are missing from it.
During "pamphlet reading hour", Dextor's Mom refers to Dexter by his correct name rather than Dextor despite that she's not supposed to know his real name.
When Dexter becomes upset over his breakfast he is in his pajamas, but when he breaks his vitamin capsule he is in his regular clothes.
