Jericho - Season 1 Episode 2 A Jug of Wine, a Loaf of Bread, and Pow!
Overview: The good guys use a French boys choir to thwart the Germans. The choir cycles through town singing, each carrying a large loaf of bread in the basket on the bicycle. Cleverly hidden inside each loaf is a stick of dynamite (thus, the title). The dynamite is used to blow up the German subs sitting in the harbor.
