So, I'm on my Veronica Mars watchthrough, and the Lost number sequence is shown (4, 8, 15, 16, 23, 42.)
I checked the air dates of the episodes, and I'll be damned. Did any of you notice it way back when it was still fresh?
Edit: Image added, it's from the episode "Donut Run" (Season 2, episode 11.) Screencap from thewb.com
