I have a 'thing' about banana splits.
When my da was first working, he was a soda jerk. Like... literally he pulled the soda taps to 'jerk' them to carbonate. And he did ice cream stuff. He taught me about lemon, cherry, chocolate and vanilla cola before it was something you could buy. And he taught me about banana splits.
Peanut butter on the bananas. THEN the holy trio of ice creams. Never top an ice cream with like toppings; no strawberries on strawberry ice cream, kind of thing. And.... enjoy.
