Birth control

There were these three girls who were getting married and they all met at
the marriage counsellor's office to discuss the options of having or not
having a baby right away.
There were two city girls and one farm girl. The counsellor asked them if
they planned on having a baby right away or were going to wait awhile.
They all said that they had discussed this with their potential
husbands and had all agreed to wait awhile. Well, the counsellor asked the
first girl what type of birth control she planned to use. Her answer was,
"The rhythm method". "That will work," said the counsellor, "but only if
you keep a good record."
He asked the second girl what system she planned on using. "I plan on using
birth control pills" she said. Again he said, "Yes that will work as long as
you don 't forget to take them".
He then asked the farm girl what system she was planning on using. Her
answer was, "The bucket and saucer method." After a short delay, he told
her that should also work. He asked them all to come back in one year on a
specific date for a follow up on how things were going.
They all met again one year later and the two city girls were pregnant.
Only the farm girl was still slim and trim. Well, the counsellor asked the
first girl what method she used and what went wrong. She replied, "I used
the rhythm method but somehow got my notes mixed up and, well here I am,
going to have a baby."'
He asked the second city girl what method she used and she replied, "The
birth control pill . But we were camping one weekend and I didn't have my
pills with me and as you can see, I too am going to have a baby."
He turns to the farm girl. "I vaguely remember you were going to use the
bucket and saucer method. Now I must admit that I don 't have a clue what
the bucket and saucer method is. Will you explain it to me as I see it has
worked well for you."
She replied, "Well, we always make love standing up, and since I am quite a
bit taller than my husband, he stands on a bucket turned upside down.
Now as we are making love, I watch his eyes, and when his eyes get as big as
saucers ....
"I kick the bucket out from under him".
