1 c. sugar
5 c. water
1 (6 oz.) can frozen lemonade
1 (12 oz.) can frozen orange juice
1 (46 oz.) can unsweetened pineapple juice
4 bananas, mashed
1 (32 oz.) bottle 7-Up
1-2 c. vodka

Mix the first 5 ingredients and freeze for 24 hours. Take from freezer 1 1/2 hours before serving. Mash the 4 bananas and add to the above mixture. Add the 7-Up and 1-2 cups of vodka, depending on how strong you want it to be. This will be slushy when served.

NOTE: This must be done ahead, and must be frozen before preparing.
