I really can't tell if people on this thread are being serious or sarcastic...
Sugars can really help near the end of bloom, but you have to know what you are doing - or - the results can be disastrous. As others mentioned, adding sugars feeds the soil microbes - not the plant. These microbes will temporarily sequester the N in the soil - which is what you want near the end of flower. However, once the microbes die, they release all that N back into the soil (plus a little extra) - which is what you don't want!
Amount of sugar and timing is key. I haven't found much diff in molasses vs white sugar tests (save your money). A quick search on this site will yield all the deets you need.
