Years ago, I had him marry one of my sims....and was so horrified at how the baby looked when she grew up to be a teenager :D His facial features and jaw structure are so odd, that it did not genetically mesh well with my sim's!

The Show Business Career Reward (Dr Vu's Cosmetic Surgeon) might be of use; however if applied, original genes are still carried on to the next generations, so future generations may also need to make use of this item. :)
Personally I like that Nervous Subject has such an interesting face - so much so that in my game, I tried to make his son, Major, look like Nervous as much as I could with his hair style even though he had fair hair like Erin! :)
