The other morning Jeff got up with our early birds at 6 a.m and let me sleep in a bit. They were all hanging out watching cartoons, and Jeff didn't have a shirt on. Alex came over and pointed at his chest.
"What's that, Daddy?" he asked.
"It's my nipple, buddy," Jeff replied.
"A nickel!?" Alex said.
Jeff started to laugh and before he could answer, Isaac pulled up his shirt, pointed to his own nipple and asked, "Is this a penny?"
Because a penny is smaller than a nickel, you know.
