My Dad called me just before his 75th birthday and asked me to bring him a cake to his birthday dinner, because Mom had him on a diet and I was under strict orders to not mention that he asked for a cake. He loves chocolate cake and coconut so I thought if I was taking the wrap for his birthday cake I was going to make it an impressive one
