If all the cows say moo it's best to moo in agreement otherwise you'll have to come up with some explination as to why they are all wrong and you disagree with them. However if all the cows are in one pond it can be rewarding to try another pond unless it has leeches, in which case its best to prepare yourself with a bottle of rubbing alcohol. If you do not have rubbing alcohol try a raw steak in hopes the leeches will prefer the steak to your flesh, though I can't really blame them if they don't...
