There was this 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 no where 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's waiting for his order of pork, the president of his congregation walks in.  He sees the rabbi and asks if he could join him for dinner, and the rabbi has no choice but to agree.  A while later, the waiter returns with the rabbi's meal.  He takes the cover off the large platter, and there is a whole roast pig, with an apple in its mouth.

The congregation president is more than a little shocked.

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