A blonde goes into her local pet shop in search of an exotic pet. As she looks about the store, she notices a box full of frogs. The sign on the box says: "Sex Frogs! Only $50 each! Comes with complete instructions."
The blonde excitedly looks around to see if anybody is watching her and whispers to the man behind the counter, "I'll take one of the sex frogs!"
As the man packages the frog, he quietly says to her, "Just follow the instructions."
The blonde nods, grabs the box, and is quickly on her way home. As soon as she closes the door to her apartment, she opens the instructions and reads them very carefully. She does exactly what the instructions tell her:
Take a shower. Splash on some nice perfume. Slip into a very sexy nightgown. Crawl into bed and place the frog beside you and the frog will do what he has been trained to do.
