Combine the 1/4 cup corn syrup, brown sugar, and butter in medium sized saucepan. Cook over low heat, stirring occasionally, until mixture begins to boil. Remove from heat. Add Rice Krispies, stirring well. Press evenly in 9 inch pie pan to form crust. Stir together peanut butter, fudge sauce and the 3 tablespoons corn syrup. Spread 1/2 the peanut butter mixture over crust. Freeze until firm. Allow ice cream to soften slightly. Spoon into frozen pie crust, spreading evenly. Freeze until firm. Let pie set for 10 minutes at room temperature before serving. Warm remaining peanut butter mixture and drizzle over top.
