Bob and Eliza Pancakes

I kind of started a challenge with them when I got DU. They had a son (not Iggy from the gallery but I did name him that) and he went to uni. He married Olivia and they had a son, Oliver. Oliver went to uni and then married Cassandra - they had twin boys so they both went to uni and they married Summer and Liberty. I am up to the 7th generation and they have to marry an available premade sim in their town before they can move on to the next town (I play with aging off so all the premades are still there - some I have to play for a while if I need to age them up like I did with Olivia). They always have boys - every generation. I believe I have been through many of the degrees already- trying to do a different one for each - all got A+ honors so far! My avatar is Iggy and his son - he took robotics or Physics: Mechanical Engineering.
