An attractive woman entered a pet shop. When the clerk offered
 assistance, she explained that she was recently divorced, and was
 looking for a small-ish dog for company.
 
 The clerk explained that the name of the store was 'Exotic Pets'
 and that, unfortunately, they did not stock cats, dogs, fish or
 any commonplace pets.
 
 He did say, however, that he had something which might be ideal.
 He took the woman into a back room. He walked over to a terrarium,
 and pointed proudly to a large bullfrog which sat inside it.
 
 "Would that suit your needs?" he asked.
 
 The woman answered, scornfully, that she hardly thought an
 amphibian would be a suitable companion.
 
 "Ah," replied the salesman, leering, "but this 'amphibian' has
 been carefully trained ... to perform oral sex upon women."
 
 At this the woman's eyes lit up.She eagerly negotiated a price of
 £500 for the frog, and left with it in her expectant possession.
 
 Arriving home, she drew a bubble bath, poured a glass of champagne
 and relaxed in anticipation. When she was thoroughly mellow, she
 dried herself, and arranged herself, nude, upon her bed. Parting
 her thighs, she placed the frog between them, closed her eyes, and
 waited.
 
 Nothing happened. She prodded the frog. Still nothing. She moved
 it up further toward her body. Nothing. She ordered it to perform.
 No response.
 
 After an hour of this frustration, she lifted the phone, and
 called the pet shop. When the clerk answered, she complained
 loudly that she had been cheated.The clerk apologised profusely,
 wrote down her address, and said he'd be right over.
 
 Ten minutes later, he knocked on the door, and the woman answered,
 wearing a nightgown.He asked her to demonstrate the problem. She
 obliged, by disrobing and assuming her former position, with the
 frog in place. The frog made no movement.
 
 "You see?" she asked, petulantly.
 
 "Yes, I do," said the man. Then, addressing the frog as he removed
 his necktie and shirt, he said, "Now, I'm only going to show you
 this one more time..."
