Alien versus Predator

Alright, listen up, buttercup. This joke is funny because it sets up two ridiculous fights. First, you got "Alien vs. Predator," which is already a wild matchup. Then, it hits you with "Cosby vs. E.T."! The Cosby part is dark because of what that dude did, drugging women. Now, you probably don't know any of that because you are dumb, but that is why it is a joke.
