If Lawson got married, how would he be able to post a butt ton of pics of himself, the "hot" fundy guy, holding random babies and toddlers all over the land? Once they were his kids, no one would care.
My sister is a blond, not any where near Tim's level of blond, but a blond and has very dark eyebrows. People constantly insist she dyes her hair. The closest she's ever come is using Sun-In and peroxide back in the day to make it blonder, but she stopped doing both of those a good decade ago.
