Hope for the best and expect the worst, when Bart, Milhouse, and Martin pull their resources together to buy a brand-new model kit that brings them together in more ways than one. Then, Principal Skinner and Bart enter into a game of "tag," one sprayed all over school property. And when Lisa gets a bump on the head, Bart tries to convince her that she has a reputation as a mischief-maker. Add in a trip Mexico, a nuclear nightmare near-miss, vikings, vampires, making faces, alien races, acting strange, climate change, and you have the makings of a catastrophe of biblical proportions or maybe just an ordinary day in the life of Bart Simpson! Collects Bart Simpson #63-67.
