They were the only ones who knew that the angel on top of the tree was actually a garden gnome that had bitten the [older brother] on the ankle as he pulled up carrots for Christmas dinner. Stupefied, painted gold, stuffed into a miniature tutu and with small wings glued to its back, it glowered down at them all, the ugliest angel [he] had ever seen, with a large bald head like a potato and rather hairy feet.
