Guido lives downstairs in the same building as K.P., Denton, and 'Mazing Man.
He considers himself a tough-guy, ladies man.
He was the first to wonder how 'Maze earns his income. He imagined that it all came from the aluminum cans that 'Maze collects and recycles. "That five cents a can adds up!" Little did anyone realize that 'Maze had won the Publishers Readinghouse Sweepstakes.
After 'Maze helped Buddy, the drunk across the street, Buddy threw up on 'Maze's shoes. 'Maze tried washing his shoes, which didn't wreck the wash machine, but did ruin his shoes. He and K.P. went shoes shopping at the mall, and found that Guido works in not one, but three different shoe stores as a salesman.
