Combine crust ingredients in a small bowl. Press the mixture on bottom and sides of a buttered 10 inch pie pan.

FILLING:

1 envelope of unflavored gelatin
1/4 cup of  cold water
1/3 cup of granulated sugar
2 tablespoons of  cornstarch
1/8 teaspoon of  salt
2 cups of canned eggnog
1 1/2 (1 oz.) squares unsweetened chocolate, melted
1 teaspoon of vanilla extract
2 tablespoons of  rum
1 cup of  whipping cream, whipped

Sprinkle gelatin over water to soften. Mix sugar, cornstarch and salt in top of a double boiler. Gradually stir in eggnog. Cook over hot, not boiling water, stirring constantly until thickened. Remove from heat and stir in softened gelatin until dissolved. Divide filling in half. Add melted chocolate and vanilla extract to one half. Set aside. Allow remaining half to cool; then fold in rum and whipped cream. Pour the rum-flavored mixture into the pie shell. Let set in refrigerator. Pour chocolate mixture on top. Chill at least 6 hours or overnight. Several hours before serving, make topping.
