The Simpsons is a TV show that’s never been afraid to merchandise itself to death. Simpsons clocks, Simpsons action figures, Simpsons telephones and Simpsons asthma inhalers have all hit stores in the past – but that’s just small fry.

The Simpsons Movie is coming out this month, and it looks set to be this summer’s best attempt at dragging out what would have been a diverting enough 24-minute TV show into a two-hour dramatic movie. But, much more than that, The Simpsons Movie is the perfect opportunity for Simpsons bigwigs to churn out a brand-new procession of cash-in Simpsons merchandise, including the zenith of opportunistic cash-in merchandise – turning a bunch of 7-Eleven stores into replica Kwik-E-Marts full of Simpsons products like Krusty O’s cereal to Squishee Slurpees to Buzz Cola. However, die-hard Simpsons fans are boycotting the promotion, upset that each box of Krusty O’s doesn’t come with a jagged metal Krusty O that will hospitalise them in the same way that Bart was in episode 125.
