There was a rabbi in a small town and he was really curious about why so many people ate pork. He really wanted to try some, but there was nowhere in town he could go and not be seen. One weekend, he made an excuse and traveled to a distant town, went into a restaurant, and ordered the first pork item on the menu. 

While he was waiting for his order of pork, the president of his congregation walked in. He saw the rabbi and asked if he could join him for dinner, and the rabbi had no choice but to agree. A while later, the waiter returned with the rabbi's meal. He took the cover off the large platter, and there was a whole roast pig with an apple in its mouth.

The congregation president was more than a little shocked.

"What a fancy place," explained the rabbi quickly. "Just look at how they serve the apple I ordered."
