Two gay men decide to have a baby.
They mix their sperm together and have a surrogate mother artificially inseminated with it.
When the baby is born, they rush to the hospital.
A dozen babies are in the ward, eleven of whom are crying and screaming.
Over in the corner, one baby is smiling serenely.
A nurse comes by, and to the delight of the gay fathers, she points out the happy child as theirs.
"Isn't it wonderful?" one gay says to the other.
"All these unhappy babies .... and yet our baby is so happy. This just proves the superiority of gay love!"
The nurse says, "Oh sure, he's happy now, but just watch what happens when I pull the thermometer out of his ass!"
