Did anyone else notice the April Fool's Day gag in today's comic section? There are three comics (maybe more) with the same joke: Pearls Before Swine, Foxtrot and Get Fuzzy.
There are slight variations, but all three strips basically have one character using a ouija board as a ruse to harm another character. In the case of "Foxtrot," the plot seems most forced. Since although Jason has an antagonist relationship with his sister Paige, it doesn't usually manifest itself in violence.
