Buy a round for an entire bar in Ireland.

This one is fun. I've never been to Ireland, but I grew up near Boston and have met my fair share of Irish people. Things I share with Irish people:

• A love of beer
• An affinity for castles
• The ability to dance

Good enough for me! According to Kayak.com, it would cost about $850 to fly from Reno to Dublin two weeks from today. http://www.kayak.com/#/flights/RNO-DUB/2012-05-01/2012-05-08. That's not bad!

Let's assume our Irish pub has 30 patrons, and a pint of Guinness costs approximately 5 Euros. At a current exchange rate of 1.3116 Dollars to Euros, each pint costs $6.558.

Total Costs:

• Round-trip flight to Dublin - $850
• Miscellaneous transportation to pub - $50
• Beers for patrons of pub - 30 x 6.558 = $196.74 
• Total: $1100

It seems easy, honestly. I could get up and do this next week!
