The day after Superbowl Sunday.

As a result of our country's tradition on Superbowl Sunday to collectively eat the most deliciously unhealthy foods known to man (e.g. buffalo wings, pigs-in-blankets, pizza, mozzerella sticks, chips & dip, sloppy joes, french fries, burgers etc.) and collectively drink billions of bottles of the cheapest beer, there is no other day of the year to beat the sheer mass of our collective poops, than the day after Superbowl Sunday. I therefore declare it, National Poop Day.
Pat: Hey man, you taking off of work for National Poop Day?
