I was watching Veronica Mars tonight (a shocker, I know) and midway through the show, I thought to myself, "is that Jonathan Taylor Thomas in this episode? Or am I crazy?"
Great news! I'm not--JTT definitely starred in one episode. He's a bit stockier than I remember and he was pretending to be a crazy guy, but wow, JTT just brings back memories of the '90s.
On a side note, Zachery Ty Bryan, who was also on Home Improvement, also starred on Veronica Mars an episode or two earlier. Random, indeed.
