If I gave you a hypothetical sack of stones, with a hypothetically infinite supply of stones, and you saw a hypothetical flock of birds sitting on a hypothetical power line, would you kill two birds with one stone or one bird with two stones? If you really think about it, the people who came up with the phrase "Two Birds With One Stone" were probably just lunkheads looking to become famous, because everyone knows that when you have a hypothetically infinite supply of stones, there's no real point to killing two birds with one stone rather than two birds with two stones, unless of course you're trying to kill both birds without scaring one away first.
