That reminds me of a couple of very old jokes.
A lady goes to the doctors 'cos she thinks she's pregnant.
Dr confirms she's pregnant.
She asks the doctor how she can ensure the child grows up being polite and well mannered.
Dr tells her, it's not a child, it's twins.
She repeats the question.
The doctor says children can be influenced while they're in the womb, so just be polite and kind during your pregnancy.
Sure enough, all through her pregnancy, she's giving up her seat, opening doors, loads of after you, no, after you, etc.
At the due time, no sign of the twins. The doctor suggest waiting a few days.
The few days turn into weeks, which turn into months. Eventually, after a few years the doctor agrees to a cesarean.
Inside the womb, they find two little fellas, one says, "after you", the other says, "no, I insist, after you".

A lady goes to the doctors 'cos she thinks she's pregnant.
Dr confirms she's pregnant.
She asks the doctor how she can ensure the child grows up with an appreciation of music.
Can she influence the children during the prgnancy? Yes, certainly he tells her. Listen to music as much as you can, It'll be soothing for them, and you never know it might influence them in life.
She's listening to music at every opportunity.
At the due time, one of the little fellas arrives but there's no sign of the other one. The doctor suggest waiting a couple of days.
After a few days, the doctor suggests she eats a straw hat. A straw hat? Yes, he says, I've know it work before.
Still no second twin.
After a few weeks, still no twin. Doctor suggests she tries eating a guitar. A guitar? she asks incredulously.
Yes he says, I've known that work as well. So she laboriously chews her way through a guitar.
Weeks turn into months, months into years. Years later, still no twin, so the doctor says there's no alternative, we must perform a cesarean.
Sure enough, on the operating table, they open her up and find the other little fella, wearing a straw hat, strumming the guitar and singing, "you got my brother but you dain't get me, doo dah, doo dah!"
