what's the difference between a dead fetus and a bowl of ice cream ? one tastes good , the other is fun to eat  for other reasons
Don't  you think it is wrong to joke about dead babies?
No one's gonna tell me I'm wrong, that fetus is just a blob of deformities.
Regardless of the life stage of a fetus it still offensive to tell these type of jokes. I would really recommend not saying these type of things because people could look at you in a weird manner.
