1 (16 oz.) pkg. cream cheese
1 can Eagle brand sweetened condensed milk
3 1/2 oz. bottled Key Lime juice (Grandma's Pantry has it)
1 graham cracker crust in a deep pie dish

Cream the cream cheese, add can of condensed milk and whip, whip, whip and whip again. Add the lime juice and whip, whip, whip. The more beating, the better the pie. Pour into graham cracker crust and top with Cool Whip or whipped cream.
