Onions

Onions are the sliced-up remains of an edible flower bulb in the genus Allium. They are commonly included on various burgers and sandwiches. Ronald McDonald, prior to his horrific death in an industrial furnace at a steel mill in the Chicago area, was known for his curious habit on eating entire raw onions as if they were apples. He was also fond of a peculiar and repugnant liquid called "onion tonic", which he is believed to have brewed himself. He claimed to have read in some magazine (doubtless a tabloid) that onions increased "vitality", boosted "brainpower", and extended lifespan by 5-10 years. As a result, the maladjusted clown often "reeked of onions", making him difficult to work with for his commercial co-stars.
