“If I do my homework, I’ll get good grades. If I get good grades, you’ll send me to university. If I go to university, I’ll graduate and get a job. If I get a job, I might get fired. If I get fired, I could go bankrupt and lose everything. That’s why I didn’t do my homework!”—Cartoon by Randy Glasbergen
