Subject: Click on his nose. Several times!
This is an alcohol test: If you pass it, you can keep drinking, if not, it's time to stop. Follow the simple instructions below:
1. Click on the man's nose
2. A new window will open - click on the man's nose again
3. For each time you click on his nose, you can drink another glass of wine!!!
