Right, so when p > 0.05, they don't reject the null hypothesis... thus "we found no link". The one panel where they do find a link does read "(p < 0.05)".

The 2008 Christmas Special had more panels, though a lot of them were just black.
XKCD Loves the Discovery Channel had the same number of panels as this comic, and far less repetition.

Quick, someone search for secret codes!

I enjoy recursive signatures.
