Get a dollar (any currency) and wipe human shit on one side of the dollar. Cake it on thick. Then apply it shit side down outside of any popular pedestrian crossing. Hide in a car and watch as the unknowing victims grab the dollar and get shit all over their hands. Then enjoy.
Jill screeched when she noticed shit was all over her after picking up the shit dollar, then proceeded to wipe it on her boyfriend Mat.
