Challenging yourself to eat an entire flavored pie in about a day. To do this, one must walk with their head held in shame down the frozen food aisle in your nearest 24 hour Stop & Shop (It is easier to buy at 1:30 am because not many people will be around to view your choice of gluttony) After pie is purchased and taken home, one must make sure it can be hid in back of refrigerator from view of family members. The challenge should be done in moments of extreme sorrow or happiness. You may also take extreme measures and eat pie while family is in the next room.
Warning - The pie challenge should only be done when one knows they will not be doing any strenuous activity and/or exercise the next day.
