WHAT DAY?

Tonight at supper, I was "discussing" with the boys that they  needed to take a shower tonight.  Little T was a bit obstinate about that situation.

Being the analytical 6 year old child that he is....here's a math problem that he came up with to argue with me.....

Fact 1:  I said.."You haven't taken a shower TODAY."

Fact 2:  He said....."But I took a shower THE DAY AFTER YESTERDAY!!!!"

Query:  What is the sum of all the products? 

Write your answer in simplest form.  :)

P.S.  I won this math contest.
