Update: As Paul points out in the comments, the rounds of this game could go by fast and furiously. Therefore, you may want to consider a non-alcoholic beverage. I thought about shots of espresso but that would probably keep me wired until Pentecost. So I may be chugging orange juice. Also, before you drain your glass, remember to say a prayer for the success and safety of the Pope's journey as well as a prayer for the enlightenment of whichever Catholic naysayer prompted you to quaff your beverage.
Update #2: If you want to see authentically Catholic coverage of the Pope's visit, go to the EWTN website. They have streaming live video of the major events as well as faithful analysis.
