My Easter Ham

This year I am going for the big challenge. I am cooking for my parents, grandmother and some friends for Easter dinner. Honestly I am nervous!!! Not because I will cook anything deadly, just because I have a 18 lb ham. My friend David called me a few weeks ago and said the Auburn University Meat lab were selling their hams for 2.09. I of course knew it was 2.09 a pound but he thought it was 2.09 for the entire ham. One could surmise he has not cooked a lot. Anyway...So I said put me down for a whole ham, thinking it would be 10-12 lbs. I got one of the smaller ones there...these pigs were huge!! So now I am realize that my ham will be cooking in the oven for 5 to 6 hours. What have I gotten myself into? Any recipes for leftover ham..we will definitely have some!!!
