From the Land of the Lost wiki fan site:
"The Sleestak are a reptilian bipedal humanoid species. They have a thin but wide-set mouths and large, round black eyes that are averse to light. Covered mostly in green scales, their bellies are yellow. Sleestak also have claws on their feet and on their hands, with a horn protruding from the top of their heads. They breathe with a pronounced hissing sound as if breathing through congestion. This is probably due to their wide set mouth and flat nostrils. The Sleestak now are a degenerate race that have lost much of their knowledge and culture. They have come out of the Era of Intelligence..."
Sounds a lot like the Democratic Party and their lizard-people overlords.
