Ah, rum. Did you know that grog, a mainstay of the pirates was rum, water, sugar and lemon or lime juice. It is actually pretty good and the citrus kept scurvy away. Even on military ships men were issued grog once a week.
Walk the plank - a great idea for our pirate party! We had a Pirate swimming party and put the across the baby pool. The kids had to walk the plank without falling in the water. It was the best part of the party.
