Since this was not accepted to feature in Dark_humour on the theory "it's a comment reply", I'll explain.
In the late 1960's "dead baby" jokes circulated in high schools. This was the most popular one:
"How do you make a dead baby float?"
"One dead baby, two scoops of ice cream, ..."
Awhile back I posted a meme with that in the Dark_humour stream and others picked up with some new jokes.
