I loved beef dripping, big slices of white bread soaking it all up. I did the same thing with the bacon fat in the grill pan. Just think of the cholesterol!
On the crazy calories theme, my great uncle used to make some rather Elvis-esque sandwiches with me: two slices of thick white bread, butter, strawberry jam, then cut into 4 pieces and battered before being deep fried until the batter was golden and crispy and the jam had gone molten.
