On this week’s show: "Guys, how do I blow up my car?" A low-budget film director wants some advice on how to turn his Ford LTD into a mushroom cloud. In this week’s “Stump the Chumps,” we rip a page from a rock band’s tour diary – how many miles did Bo get out of the Jalopy Posse van? Plus, Reverend Dave may have to ask forgiveness for those things he said when his keys got stuck in the ignition. Listeners offer a few choice new words that ought to be in the dictionary – like the personal Car Talk favorite, “stupiphany.” That and more, in this week’s self-destructing hour of Car Talk.
