Episode 4260

Oscar is taking a computer class in Grouchology where the golden rule is to observe, record, & annoy. The 1st question that he must investigate is "What do worms like to squirm on best?" Professor Nikola Messla (Jason Jones) tells him he must set up an experiment where he observes (watches closely & carefully), records (writes down what he discovers), & annoy someone while he is doing it. Oscar heads over to Hooper's Store where he pours coffee grinds & olive oil all over Alan's nice clean counter. He observes the worms in the mess, & marks down what he sees on his chart. He succeeds in annoying Alan, & concludes that most of the worms like to squirm in the olive oil.

The second question to investigate is "What stinky smell will make people scram?" He finds Gina & Leela playing cards & tries to make them scram with garlic, an old piece of cheese, & finally his own stinky socks. He observes, records & annoys them both as they finally flee holding their noses from his smelly socks.

Oscar 's final question is "What noise is loud enough to wake up Luis & Maria?" He blasts a vuvuzela horn & observes & records that it wakes up Maria, but not Luis. As she shouts at Oscar to let her get some sleep, Luis wakes up from her yelling. Oscar concludes Maria's shrill screaming is the loudest noise of all. He reports what he discovered in each experiment to Professor Messla & collects his stinky diploma in Grouchology. Now it's time for a loud, annoying party.
