Significance of Milk?

What in the world could be the signifance of 3 gallons of milk? Or even if it was 1 or if it was 6? Well let me tell you. I buy a lot of milk on Mondays because it's only $1.99 at Shell Gas Stop in Volga. No limit. As many as you want. It's a great deal! Of course, our family goes through milk like crazy. Anyhow, EVERY Monday is Milk Monday.
