Here's an easy one.
Mix a drink. No shots or pure alcohol. (Rum and coke here, at least once noon rolls around.)
1. For every person who posts "check email again and nothing yet" take a sip.
2. For the first person who posts "woot I got one" finish your drink.
3. If that person was you, finish your drink and go make yourself another.
Step 1: make 15 zam accounts
Step 2: make 15 "woot" posts
Step 3: profit
