Or the day before that.

[Peripheral]

Today I will make a major change. I will say OOHHH instead of OWW when my pains start. Huh, today will be the same as yesterday which was the same as the day before or the day before that. Who said, "Or the day before that" and in which episode?

Good morning Peri

And a Good Morning to you Roger. You are right of course.
Have a nice day.
