At funerals in Foon, everyone gathers around the deceased and eats food off of them. It's best to go to a funeral of a large person because there's more room for food. (Childrens' funerals are the worst.) Then people tell fables. Often people will have sex (which is considered by many to be "the best"). Erotic dancers are sometimes employed to arouse the bereaved1.
After that, you place pets on them, which will dance. The "deceased" can then say whether not they are dead. If they don't say anything, you can cut off their heads.
Finally, you cut everything apart, throw the pieces in a lake, and wave goodbye.2
