Slow Mom, Fast Mom!

Little Freddie’s mother was in the hospital, and he was paying a visit to see his new brother. He wandered into an adjoining room which was occupied by a woman with a broken leg.
“Hello,” he said. “How long have you been here?”

“Let me see your baby,” he then asked.
“Why, I haven’t a baby,” the woman replied.
“Gee, you’re slow,” said Freddie. “My mama’s been here just two days and she’s got one.”
