On the Unofficial Sam and Max Website's episode guide, they are missing an episode called, "Fools Die on Friday."
It opens with Max burping and Sam trying to guess what he had for breakfast. It's about Lorne hijacking a plane and trying to fly it into the Statue of Liberty to get Sam and Max's attention.
This episode is on the homemade DVD auctioned on eBay a few months ago.
Please put this episode on the episode guide.
