I was the one with the 2-year-old loudly proclaiming "I love hairy balls!"
Well, technically, it was "I love hairy ball". She was happily clutching one of those balls that is like a giant koosh ball, which she apparently thought was "hairy".
I didn't even realize until she'd been saying it for awhile. I said, "Yes, dear, I know you love hairy balls." Then someone gave me this look...and it occurred to me that it might sound a bit odd.
Thankfully she then proceeded to sing the "I love you" Barney song at the top of her lungs. This is the first (and probably last) time I was ever glad to hear that song.
