An Amish girl is riding along with her mother on a horse and cart

Feeling the cold, she cups her hands and blows on them. Seeing this the mother leans in and gives her daughter a little life lesson.
"When its this cold and on long journies like this place your hands between your thighs my dear". This good piece of advise does the trick.
The next day the neighbours son comes by on his horse and cart just as the Amish girl is leaving the house to head to the working fields and offers her a lift. Casually he remarks on the cold weather and that his hands were feeling the cold. Eager to pass on the nugget of good knowledge learnt the day before she suggests he warms them up by placing them between her thighs. The next day, again the boy picks up his naive neighbours daughter and this time tries to go a bit further by hinting that his nose is numb from cold. Again the Amish girl helps him out by telling him to place it between her thighs. On the next day the boy goes for broke and complains that the bittingly bitter wind is going right up his trouser leg and thus his penis is frozen stiff. That night the girl comes home looking very flustered. Her concerned mother asks " What on earth is the matter girl?". She tells her mother everything ending with the boy placing his penis between her thighs, eyes bulging the mother screams " Then what happened!?" . The girl looked confused " It melted...."
