Crockpot Mac and Cheese

Stolen from the internet, but it has been a huge hit at the office:

8 oz elbow macaroni
4 c. shredded cheddar
1 can (12 oz) evaporated milk
1 1/2 c. milk
2 eggs
salt and pepper to taste

Cook macaroni and drain. Mix macaroni, 3 cups of the cheese, and all other ingredients in the crockpot. Sprinkle Remaining cheese on top. Cover and cook on low 5-6 hours, or until firm and golden around edges. Do not remove cover or stir while cooking.
