Get a 9X9 square cake pan. Cover the inside with foil. Break graham crackers into 8 squares. Lay 6 of the squares then break the last two squares into 4 pieces. Put 3 pieces at the end to fill in and save the 4th for the top. Blend the strawberries and bananas together so it's just a little bit chunky but mostly smooth. Pour into a bowl and mix cool whip in till blended. Spoon out mixture on top of graham crackers evenly then top with graham crackers the same way you did on the bottom. Cover and put in freezer. Should be ready in 4 hours.
