Yes we have a formula.
1.5oz of Don Julio Anejo
1oz of Grand Marnier
Juice of one lime
Sweet and Sour mix
Ice (chrushed)
Salt on rim.
Stir drink and repeat. Until dart hits name on dart board. (MGD is in the bullseye.)
Daddog, gave me the recipe.

Actually,
We have an Excel spreadsheet system that has been in place for a couple of years. It tracks who has been CiC, and attendance.
Vmf-101 was CiC in "Bangkok or Bust" in September. You were probably due this time, and will most likely have the duty next event.
