A man is out in his row boat when suddenly a passing speed boat raises huge waves and the man's oars fall overboard! He is stranded out in the middle of the lake!
After about two hours, he sees another row boat going by with a man and two women in it! The first man yells, "Hey buddy, can I borrow one of your oars?" The other man yells back,
"They're not whores ... they're my sisters!"
