Headlined as "ALIEN V," the panel is a take off on the science fiction horror movie series "Aliens," which is known for its gore, including scenes where baby aliens burst out of people's chests after gestating there for some time.
A Republican Elephant is in the examining room at a hospital being checked out by a doctor. The doctor has his stethoscope to the elephant's chest. He says to the elephant, "Sounds like you've got a Buchanan in there. Not good, especially if he tries to get out."
POSTSCRIPT: Should have listened to Buchanan's warning about Aliens while there was still time.
