Cracker Barrel Old Country Store Lemon Ice Box Pie

1 (8- or 9-inch) graham cracker crust
1 (14 ounce) can Eagle brand sweetened condensed milk
3 egg yolks
3 ounces Minute Maid pure lemon juice
4 ounces Cool Whip, thawed
14 vanilla wafers

Combine milk, yolks and lemon juice with wire whip. Pour into pie shell. Arrange vanilla wafers around pie, pushing into the filling so only 1/2 the wafer is showing. Spread Cool Whip over top evenly, and cover with plastic wrap. Put into freezer for at least 2 hours.

Serve very cold.
