Psst...buddy. Over here.
You looking to get some party water into the game? Don't worry about my trench coat, man. I'm here to help you.
Stadium alcohol is highway robbery. A Bud Light is the price of lunch and a mixed drink will cost you a second son. Why settle for these prices when there are other ways?
I'm not telling you to break any rules—I'd never suggest any unlawfulness on your part. All I'm saying is that if you were trying to get some of that sweet nectar into the game, this is how you could do it.*
Don't worry if it's weird; just watch and learn. This is how to sneak beer into sporting events.
*Do not drink if you are under 21 years of age. It's the law, dummy.
