OK this prank is not only cheap but it is very simple to make. My friend is in the military and when he came back home for a few weeks we decided to prank him. its only fair since we always try to out prank each other.
so this is what you need
2 quarts of mint chocolate ice cream (about 1.97 at wall-mart )
1 pack of wasabi (about 1.50 at wall-mart)
