I just ate a piece of cake. It tasted a little funny. Mom had found it in the freezer. When I mentioned "it tastes a little old", she remembered where she had seen that icing before (pink and funny). We looked up some old photos, and it turned out, this was the last remains of mom and dad's wedding cake.
They got married in 1986.
In other words, I just had a meal that was prepared five years before I was born.
