Lemon cream punch

When we ran out of sherbet at my daughter's party, we had some lemonade leftover as well as some sprite and vanilla ice cream.  My mother-in-law added them to the punch bowl and everyone agreed is was amazing!  I wish I had actual quantities to write down, but I don't.  I just wanted to add it to the blog so we can remember to try it again soon.

I would guess:
1 1/2 cups lemonade
1 1/2 cups sprite
1 pint ice cream
