It was once a sound bet when comparing dollars to donuts. You could get several donuts for $1 (USD). Today the phrase has the connotation that betting dollars to donuts is a bad bet when donuts can cost more than one dollar. This "faux bet" notion is commonly tossed around in what may be matters of trivial exchanges. When it comes to investing in a law school - far from the trivial - some of the more pessimistic may eviscerate the longstanding value of a law school degree and call "dollars-to-donuts!"
