Here's the picture: 9th grade biology. Our teacher, Bill McQuilken is lecturing about something long forgotten. He uses the word "phenomena" which prompts Jeff to shout "DO DO DO DO DO!" at the top of his lungs. The class has a collective laugh. Mr. McQuilken laughs hard enough to snort, causing the class to erupt into even more laughter, practically ending the lesson for the day and cementing Jeff into the class clown hall of fame.
Good times.
