"Where's that drum sound?"
I was looking through the spice cabinet for some Accent to use in my cooking demonstration tomorrow evening and I muttered something to the effect of, "I don't have any Accent."
Jacob, standing next to me said, "Yes, you do. You have an American accent." I just gave him a look that could be read as "Oh, that was not your most brilliant comment."
Then he grinned and said, "Hey, where's that drum sound that you're supposed to hear when I make a joke? You know the bada dum sound."
Now that one - that was worth remembering.
