Holly Berries
"They're fascinating, aren't they?" the Doctor said, holding up the bunch of holly berries. He pressed the tip of his finger against the green leaves. "Dangerous, though..." he said, pulling his hand back.
"They're just holly berries," said Amy, digging through the box of decorations the Doctor had dug out of some dusty TARDIS corner.
"They're my favourite part of Christmas," said the Doctor. "Well, aside from the snow and the presents and the food..." He grinned. "Human Christmas is so much fun! I should do this every year!"
Amy rolled her eyes and started searching through the decorations again.
