When "Kids say the darndest things!" attacks... repeatedly

I met my parents after work to go Father's Day shopping, and they brought Faith along. While I'm looking through the gardening section, my mom takes Faith inside to use the restroom. As they are walking back across the parking lot, Faith screams over to me, "Uncle Bobb! Gramma farted!"
"Shhhh!"
"Well, you did."
"It's not nice to talk about it."
"Well, you are the one who did it."

Thankfully, there weren't many people around, and most of them either didn't hear or did a pretty good job of pretending not to hear. One woman got a pretty good chuckle out of it, though.
