A guy brings some items up to the register at a hardware store, and notices a jar of frogs up on a shelf with a sign that says, "Frogs, $100.00 a piece."
The customer asks the guy behind the counter: "Hey pal, why are these frogs so expensive?"
The salesperson replies, "Why? Because they will give you the best blow-job you ever had." The customer looks dubious. "No; it's true, " the salesperson continues. "As a matter of fact, if you buy one, and take it home, and if what I said isn't true, you can bring it back for a full refund." The man buys a frog, and leaves.
The next day, the man comes back to the store to buy some other items and sees the same clerk. "Are you here to return the frog?" The man says, "Hell no!"
Later that night, the man is in his kitchen, with the frog on the counter, and there is food around, cookbooks open, pots boiling, and things frying and baking in the oven. His wife walks in.
"What the hell is going on here? This place is a damn mess! You better clean it up but fast!"
The guy just smiles, and says, "Listen, bitch; if I can teach this frog to cook, you are history."
