Randall Carlson is HILARIOUS! Pyramids, Aliens, and Laughs!

In this episode, Doug and Sean speak with Randall Carlson about
the measurements of the pyramids, the awesome precision of the
Nabta Playa rocks showing the distance of stars from Earth, and
some Jahova's Witnesses interrupt by knocking on Randall's door,
which he, of course, spins into an amazing bit of teaching.
