An Amish woman and her daughter were riding in an open buggy one cold,
blustery January day. The daughter said to the mother, "My hands are
freezing cold." The mother replied, "Put your hands between your legs.
The body heat will warm them up."
So the daughter did, and her hands warmed up. The next day, the
daughter was riding in the buggy with her boyfriend. The boyfriend said, "My hands
are freezing cold." The daughter said, "Put them between my legs, they'll
warm up."
The next day, the boyfriend is driving in the buggy with the daughter.
 He said, "My nose is freezing cold." The daughter said, "Put it between
my legs. It will warm up." He did, and his nose warmed up.
The next day, the boyfriend is driving again with the daughter and he
said, "My penis is frozen solid."
The next day, the daughter is driving in the buggy with her mother,
and she says to her mother, "Have you ever heard of a penis?" The slightly
concerned mother says, "Sure, why do you ask?" The daughter says, "Well, they
make one hell of a mess when they thaw out.
