. . . seems to be the main lesson of Warner Bros.' animated short, THE UNEXPECTED PEST. Just when you think there's no more dirt to be dug up about a particular rat, it turns out that their Pops may have assassinated JFK. Some will argue that just because the longest-serving Rodent Speaker of the House reveals that he's been a serial Child Molester all along, doesn't automatically mean that the rest of the Mouse Leaders were (or are) Chesters themselves. Sylvester decides to make a pact with the Devil Mouse to keep his spot on a Comfy Sofa in PEST. Naturally, the rodent double-crosses him, because pathological lying is a Rodent's Nature. With PEST, Warner is warning America NOT to crawl into bed with a rat, no matter how much Security seems to be offered. Sooner rather than later the rodent will stab you in the back, forcing you to hobble away from the only Homeland you've ever known on crutches, just like Sylvester here. You may think that the Rodents are speaking your language, but they're actually only interested in squirreling away America's wealth for themselves, like pack rats!
