Two brothers enlisting in the Army were undergoing their physicals. During the inspection, the doctor was surprised to see that both of the men possessed extraordinarily long penises.
"How do you account for this?" he asked the brothers.
"Its hereditary, sir," replied the older brother.
"I see, said the doctor, writing in his file." Your fathers the reason for your elongated penises?
"No, sir, our mother.
"Your mother?" said the doctor.
"Dont be so ridiculous! Women dont have penises!"
"I know, sir," replied the recruit, "but she only had one arm, and when it came to getting us out of the bathtub, she had to manage as best she could."
