A pretty young blond goes to her local pet store in search of an exotic
pet. As she looks about the store, she notices a box full of live frogs.
The sign says: "$ex Frogs! Guaranteed to satisfy any woman. Only
$50 each! Satisfaction or money refunded. Comes with complete instructions."
The blonde excitedly looks around to see if anybody's watching her. She
whispers softly to the man behind the counter, "I'll take one." The man
packages the frog and says, "Just follow the instructions." The girl nods, grabs the box, and is quickly on her way home.
As soon as she closes the door to her apartment, she reads the instructions and reads them very carefully. She does exactly what is
specified:

1. Take a shower.
2. Splash on some nice perfume.
3. Slip into a very sexy nightie.
4. Crawl into bed and place the frog down beside you and allow the
frog to follow its training.

She then quickly gets into bed with the frog and, to her surprise, nothing
happens! The girl is very disappointed and quite upset. She re-reads the
instructions and notices at the bottom of the paper it says, "If you
have any problems or questions, please call the pet store."
So, she calls the pet store.
The man says, "I'll be right over." Within minutes, the man is ringing
her doorbell. the lady welcomes him in and says, "See, I've done everything according to the instructions.. the d@mn thing just
sits there." The man, looking very concerned, picks up the frog, stares
directly into its eyes and sternly says: "Listen to me! I'm only going to
show you how to do this one more time."
