The Amazing Rabbit
Johnny the farmer is tired of rabbits always coming to his vegetable patch and eating up all his vegetables. So one day, he decides to build a big fence, 4 feet high, 2 feet below the ground (in case the rabbits try to burrow their way underground into his vegetable patch) all around his patch. The fence is very sturdy so no rabbit or any other animal could break it and there's no possible way that the rabbit could get into the vegetable patch without human help. Two days after Johnny built the fence, he found rabbit bite marks on his cabbages and carrots. No humans brought rabbits in or helped the rabbits into the patch, so Johnny was stumped how rabbits could've gotten into the patch. How did rabbits get into the vegetable patch?

Rabbits didn't get INTO the patch, they were already there when Johnny built the fence. Johnny had forgotten to get the rabbits out of the patch while building the fence, so instead of keeping the rabbits out of his patch he was keeping them in. Once Johnny realized this, he let the rabbits out and didn't have any more rabbit troubles after that.
