Something fishy is going on....

I awoke to a very strong smell of fish, which I assumed meant my wife had made fish for breakfast, but when she got home from work and also noticed the smell, I found out that not only did she not make fish, but that the smell did not exist when she left for work. So sometime between her leaving and me waking up, something that is not fish caused a strong fish smell to appear. And emptying all the trashes didn't help a bit.
