Plucky waited till the last minute to do his homework, and when he finally has the chance, he falls asleep until 7:00 AM. With no time to study, Plucky comes up with a brilliant (sarcasm) plan to build a time machine out of his clock, couch, bathtub, and lawn mower. Then, Plucky of the future comes in the time machine that he built four days later to take present Plucky back to Friday to do the homework.
