Tonight Lucas gave the boys hair cuts to get ready for their first day of school tomorrow. To keep it clean, they did it out on the back porch. At dinner, Lucas said something about how the birds can use the hair for their nests, or something like that.
Sebastian made a funny face, rubbed his head, and said, "I can't imagine the birds taking all my hair. Then I would have a bald spot."
"Then I would need a wig" Sebastian continued.
Isaac laughed harder.
"What's a wig?" Isaac asked. Apparently after laughing, he realized he didn't know what he was laughing at.
"A wig is fake hair for people who don't have their own,"answers Sebastian-the-know-it-all. "Like Grandpa. He could use a wig."
That was it. Isaac lost it! Clearly, the jokes are funnier when he actually understands what they mean!
