Cunning man

Each time the man visits this bar he has a little white box with him. The lady bartender is finally overcome with interest, and ask: “What’s in the box?” To which he replies “The most amazing frog ever. He loves to go down on women and he is really great.” She suggest she found out how how good the frog is. In the back room she takes off all her clothes, and spreads her legs apart as the man takes the frog out of the box and places him between her legs. After several minutes nothing is happening. The man reaches down and picks the frog up, and shaking him says: “Now listen, I am going to show you one more time!”
