The Cosby compound falls under attack by aliens.
Cosby 100 makes a deal with Curiosity Cosby that if he gives him the cloning machine plans he will, in return, he offers him a night with Cosbyette. Curiosity Cosby gets very excited and agrees to get the plans.
Frequency Cosby shoots the Alien with a lightning blast and Humming Bird Cosby defecates a bomb and blows the Alien's eye off. Toothpaste Cosby turns into a slippery puddle and the Alien trips, crushing Frequency Cosby.
Before the credits, we see Curiosity Cosby's body in chunks and Droopy Cosby saying "Evil. Evil C...C...Cosby, you see, R...R...Rudy". Telling us that Evil Cosby killed Curiosity Cosby.
