Lightning can do sub-satoshi payments: payments can be made conditional upon the outcome of a random event, allowing probabilistic payments. For example, Alice can pay Bob 0.1 satoshi by creating a 1-satoshi payment with 10-to-1 odds so that 90% of the time she does this she pays him 0 satoshis and 10% of the time she pays him 1 satoshi for an average payment of 0.1 satoshis.
By this logic a man and a woman (assuming they are both fertile and not using any contraception) make some fraction of a baby every time they have sex

And when they get divorced they can "split the children" for custody!
But no, because it is like if you were likely to impregnate once every ten times having sex. One of those ten times you make 100 percent of a baby.
