Avocado Pie

Again from YAAPS. I might have to make this just to freak people out.

1 avocado, chopped
2/3 c lemon juice
1 can sweetened condensed milk
1 graham cracker pie shell

Combine avocado with lemon juice and condensed milk in blender container (I use a food processor, but have also made this w/o a blender OR food processor, just using a fork). Process until smooth. Pour into pie shell. Chill until firm. Garnish with whipped cream.
