1. Visit your local supermarket, corner store, or bodega.
2. Purchase a carton of Tropicana or other similar beverage.
3. Purchase a sleeve of the smallest Dixie Cups (or equivalent) you can find.
4. Go to a bar, your place of work, a nearby Home Depot, or somewhere you won't get beaten up.
5. Pour the beverage into the small cups.
6. Put on your Yankee hat.
7. Offer the cups to passers by, friends, or associates saying each time:
"I am a New York Yankees fan, so can I offer you a shot of juice?"
That is all (although a photo would be nice).
