Why Eat The Aliens:
Aliens come here without an invitation.
They mutilate our cattle.
They probe human abductees by shoving probes up their rectum.
They perform other unspeakable acts upon unsuspecting earth inhabitants.
There are a lot of them and they seem to be increasing in numbers.
They are Kosher.
Some say they ate Elvis.
They taste good if marinated with red wine and lots of garlic.
They fool around with the Space Shuttle, when the astronauts aren't looking.
Their meat is safer than British Beef.
You can't tell them from an undocumented illegal Mexican.
