Context: We had a sales meeting today and one of our team , the soon to be married Tim , said we were out of stress balls - though I am not sure of any connection to Tim 's impending nuptials . I figured the best way to show we are not out of stress balls was to dump a box of 300 balls over him . We all had a laugh and talked about the value of the stress balls at trade shows and in demonstrations . We have used these balls at four trade shows now and people love them .

Question: What makes these stress balls so valuable ?
Options:
0. They can give them away for free at trade shows and its a form of marketing .
1. None of the above choices .
2. They hold no value , I was being sarcastic .
3. They sell them at trade shows to get a little more profit .
Answer: 0
