It's not 'bungling', it's bundling.
According to wickipedia, "Traditionally, participants were adolescents, with a boy staying at the residence of a girl. They were given separate blankets by the girl's parents and expected to talk to one another through the night. The practice was limited to the winter and sometimes the use of a bundling board, placed between the boy and girl, ensured that no sexual conduct would take place."
"When used for courtship, the aim was to allow intimacy without sexual intercourse."
Since the Amish don't use birth control, how disinterested do you think the girl's parents would be in what actually happens?
Anyway, your cynical comment is irrelevent to the overall morality and ethics of the Amish...
