This was one of my favourite treats from the Woolworth's soda fountain, when I was a wee child:

TRI-CITY WOOLWORTH'S
"BLACK COW"

8 scoops vanilla ice cream
Mug root beer--or your favourite rootbeer.

Place 2 small scoops of vanilla ice cream in four tall glasses. Pour in root beer about halfway and serve.

Another childhood favourite:

ORANGE JULIUS:

1 cup orange juice
2/3 cups dry skim milk
2 teaspoons vanilla extract
2 teaspoons granulated sugar
8 ice cubes

Place everything in a blender, cover and blend on medium speed until mixture is frothy. 1 to 2 servings.

Here's omething I invented during some downtime while working as a breakfast chef at our local Holiday Inn, back in 1982:

NANCY'S OWN CHOCO-COFFEE

1 cup premium brand hot black coffee
2 tablespoons chocolate syrup
2 tablespoons cream or whole milk
whipped cream

Stir in syrup and cream, top with a dollop of whipped cream.
