After we finished work on the deck we drove around different places selling watermelons out of the back of Norm 's truck . We got about 150 for $ 100 and sold them 1 for $ 3 or 2 for $ 5 . We figured it 'd be an evening of easy money . Only we only sold about 20 so we did n't even make back our investment .
