Evidently their "Wedding" fruitcake wasn't edible either. Hence the sale of a piece 37 years later. And, being fruitcake, it should be around another 37 years.
Perhaps it is the American version of the cake that no one likes. There must be some reason for the popularity of the dessert -- other than as an object of ridicule.

"A good fruitcake can last a long time. The high sugar content in the cake helps it keep, and if you frequently moisten the cake with liquor it can last a very long time.
A very, very long time. America's oldest documented fruitcake was baked in 1878 by Fidelia Bates, and it is still in her family today. In 2003 her great grandson, Morgan Ford of Tecumseh, Michigan, brought the cake on Jay Leno's talk show. Despite possible health risks Jay ate a very small piece of the cake. He said it smelled good but tasted crystallized. That's pretty good praise for a cake that's 125 years old. . .
Like Christmas itself fruitcake may have its origins in the ancient Greco-Roman world. A writer named Chrysippus claims the Cretans made cakes with nuts, fruit, spices and honey. I'm sure the Romans enjoyed similar treats as the celebrated Saturnalia, the pagan forerunner to Christmas. If a two-thousand year old fruitcake is unearthed I want to see Jay Leno take a bite!"
