Madagascar Easter Egg - To Serve Lemur

In the Lemur meeting in which the outsider animals and the Fousas are discussed. At the mention of the word Fousa, the lemurs all go into panic, and briefly in the panic, you'll see a lemur pop up holding a book entitled 'To Serve Lemur' screaming "It's a cookbook! It's a cookbook!"

Apparently someone at Dreamworks is a fan of a certain Twilight Zone in which aliens land on earth promising to help humans, carrying a mysterious book, 'To Serve Mankind'. Later, after humans begin to be transported to visit the aliens' planet, a man scheduled to be transported discovers a bit too late that the 'serving' in question is not 'to help' but 'to cook'.
