What to get the man who has lazy relatives

Dear Dr. Sadie,

My brother-in-law, a good friend of mine, is celebrating his birthday, but I'm not sure what to do for him. He's not the kind of person who likes to get a lot of presents or a big fuss. But he's always been very generous to me and to everyone around him. What should I do for him?

Lazy Brother-In-Law

You should not get him a present. You should not bake him a cake. You should do nothing. All you should do is throw him a surprise birthday party. Mama doesn't want a surprise birthday party so (whispering) don't tell her we're going to throw a surprise birthday party, because it's a surprise.
