Penny's Key Lime Punch

Erin brought this to a recent flyfest. I thought it was wonderfully fresh tasting.

================

Penny's Key Lime Punch

1 container of Key Lime Sherbet

1 2 liter bottle of ginger ale

1 container of frozen Minute Maid Limeade

Into a punch bowl pour in thawed limeade, add 1/3 of ginger ale, then spoon in partially thawed sherbet, allow this to fizz and settle, then SLOWLY add rest of ginger ale.
Voila!

Notes:
-- Minute Maid Limeade seems to work best. Others don't taste right in this.
-- Use a big bowl, it fizzes a lot!
