The Shepherd, The Angel, and Walter the Christmas Miracle Dog by Dave Barry
This is a funny, quick Christmassy read from Dave Barry, who always makes me laugh. I'd read some of it before, in his column (who could forget the description of why it's better to be a shepherd than a Three King because you get to wait for your cue in the church belfry closet filled with bat poop?), but it's the story of Doug Barnes who, in 1960, is playing a shepherd in the Christmas pageant. His family's beloved dog Frank is about to die, his dad gets a flat tire on Christmas Eve (and their car is infested with red ants), and the shepherds keep giggling instead of solemnly walking towards Bethlehem.
