One I heard a little girl in the park this summer yell:
"I can't run! My toe has a headache!"

One my sister said when we were kids:
"Didn't you hear me? Are you blind in the ears?"

One my other sister told me her friend's daughter told her after a day at day care:
"Every day C_________ knocks her plate on the floor and says Whoopsie daisy!. But it's not a whoopsie-daisy, Mom. It's an on-purpose daisy."
