1) Combine peanut butter, cream cheese and sugar together with a mixer or food processor. Fold this mixture into the whip topping until smooth and completely combined. Put in pie crust and let chill at least 2hours in the fridge. The longer the better though.
2) Pulse graham crackers and sugar in a food processor till it's a fine crumble. Stream in butter till the consistency is like wet sand and can be molded. Put in a pie plate and bake at 375 for 10 to12 minutes until little golden and crisp. Let cool before adding pie filling.
