Pearls melt in vinegar.

These two country boys, brothers, were knocking around one lazy summer day and thought it would be a good prank to push over the outhouse. They crept up from an advantageous direction like a couple of commandos, pushed the outhouse over on one side and headed for the woods. They circled round and returned home an hour later from a completely different direction thus, trying to divert suspicion from themselves.Upon returning, their father approached them with switch in hand and bellowed, "Did you two push the outhouse over this afternoon?"The older boy replied, "As learned in school, I cannot tell a lie. Yes, Father, we pushed over the outhouse this afternoon."At this revelation, the farmer proceeded to flail the two boys severely and sent them to bed without supper.In the morning, the two boys meekly approached the breakfast table and took their seats. Everything was quiet until their father finally said, "Have you two learned your lesson?""Sure, Dad!" said the big brother, "But, in school we learned that George Washington admitted to HIS father that he`d chopped down a cherry tree and he was forgiven because he told the truth.""Ah yes!` said the farmer, "BUT, George`s DAD, wasn`t in the cherry tree when he chopped it down!"
