cake and ice cream
Have you ever been to one of those cake and ice cream parties where they give you cake and ice cream together on a plate with a fork? A plate and fork may be okay for cake, but that's just not the way ice cream is meant to be eaten. Ice cream belongs in a bowl, and it's better eaten with a spoon.
I've noticed that the more classy the party is, the more likely you are to get ice cream on a plate with a fork. That makes absolutely no sense to me. You'd think that the classier people are, the more intelligent they would be. Do these people not realize the impracticality of their practice? Do they not realize how much better it is to separate the cake and ice cream, and to eat the ice cream in a bowl with a spoon? Having gone through the frustration of saving a cake from melting ice cream, and then chasing the ice cream around a plate with a fork only to have it become impossible to eat with a fork, you'd think these people would wise up.
The one exception is ice cream on a brownie.
