Alrighty already with the Lost signs, damn.

Stuck in the ground is a makeshift sign. It reads “4 8 15 16 23 42”.

The numbers 4, 8, 15, 16, 23, and 42 appear throughout the series "LOST", both in sequence and individually. The numbers add up to 108, another common number in the series.

We get it, someone's really into that series. Myself I've never seen an episode of it at all.
