Baby weight joke for kids

Our Lamaze class included a tour of the pediatric wing of the hospital. When a new baby was brought into the nursery, all the women tried to guess its weight, but the guy standing next to me was the only male to venture a number.

"Looks like 9 pounds," he offered confidently.

"This must not be your first," I said.

"Oh, yes," he said. "It's my first."

"Then how would you know the weight of a baby?" I asked.

He shrugged. "I'm a fisherman."
