"Clinton''s final confession" joke

Final Confession
-=-=-=-=-=-=-=-=-=-
"This one has changed for the occasion."
The President takes the day off from work to elude the press corps and Hillary. He decides to go golfing. Bill gives the slip to the Secret Service and ends up, unrecognized, at a small public course in Maryland.
He is on the 2nd hole when he notices a frog sitting next to the green. He thinks nothing of it and is about to tee off when he hears, "Ribbit. 9 Iron." The President looks around and doesn't see anyone. Again he hears, "Ribbit. 9 Iron." He looks at the frog and decides to prove him wrong, puts his driver away and grabs his 9 iron.
Boom! He hits the ball 10 inches from the cup. He is shocked.
He says to the frog, "Wow that's amazing. You must be a lucky frog, eh?"
The Frog replies "Ribbit. Luck Frog."
The President decides to take him to the next hole. What do you think frog?" the President asks.
"Ribbit. 3 Wood."
Bill takes out his 3 wood and Wham! Hole in one. The President is befuddled and doesn't know what to say.
By the end of the day, the President golfed the best game of his life and asks the frog, "Ok, where to next?"
The frog replies, "Ribbit. Las Vegas."
They go to Andrews AFB, fire up Air Force One, file for clearance direct to Las Vegas, and arrive at 4 AM, still unrecognized, at a casino. Bill says, "Ok frog, now what?"
The frog replies, "Ribbit. Roulette." Upon reaching the roulette table, the President then asks, "What do you think I should bet?"
The frog replies, "Ribbit. $300,000 on black 6."
Now this is a million-to-one shot to win, but after the golf game, Clinton figures what the heck. Whoosh! Tons of cash come sliding back across the table.
The President takes his winnings and his new buddy, First Frog and heads back to D.C. Bill sets the F.F. on a cushion on his desk in the Oval Office and says, "Frog, I don't know how to repay you. You've won me all this money and I, and the Democratic National Committee, are forever grateful."
The Frog replies, "Ribbit. Kiss me."
Bill figures why not, after all the frog has done for him, he deserves it. With a kiss the frog turns into a 25-year-old girl named Monica.
"And that, Mr. Starr, is how she ended up in my office.
