There were these two keen lady anglers who often went fishing together.
One of the ladies was much more successful and invariably would catch more fish from her side of the boat.
One day, in frustration, the other lady asked her what her secret was.
She responded, “Well, before I get out of bed in the morning, I look under the covers at my husband. If “it” is laying over to the left, then I fish off the left side of the boat. If “it” is laying to the right then I fish off the right side of the boat”.
Her partner blushed a little, then asked, “What do you do if “it” is standing straight up?”
She replied, “Well, if that happens, I don’t go fishing that day!”
