When the box arrives she takes the frog out, and reads the instructions:
"Get naked and place the frog between your legs and gently stroke its back, and it'll please you."
She follows the instructions, but nothing happens, no matter how much she strokes the frog's back. Frustrated she calls the support number on the box and a guy answers. After listening to the woman he tells her that he'll come to her house and get the frog to perform.
The support guy arrives, and puts the frog between the naked woman's legs and strokes the frog's back, but nothing happens. The guy yells at the frog, but still nothing happens.
Then he moves the frog aside, gets between the woman's legs and says, "I'm sorry he's so stupid, but I'm going to have to show him what to do."
