I fail to see the logic behind using precision instruments to mash a banana through a slice of bread. Just mash the banana straight through the slice of bread and be done with it so we can move on to the next useless demonstration.
Now in this next demonstration we will learn how to use only a sawzall, a dragline, and 150 gallons of Xylene to ease the difficult process of mashing a 24 oz. ball pein hammer through a slice of bread.
