DR Elmore - nice photo of your dad!
I am, as we speak, in the throes of making the chocolate pie for which DR Cillaliz posted the recipe. Last night, I printed both on a sheet of paper and asked my family to pick one. Since it makes 2 pies, I'll take one to the baby shower Friday and we'll have one here at home to taste. I've already had an idea for a holiday variation - use peppermint stick ice cream.
As for the peanut butter pie, I also want to make that one soon because it's my mother's favorite pie variety. If you'd come to the tri-state, BK, to visit DR Charles Pogue, I'd make you one, too!
