$NEURALSTEM INC(CUR)$ 我见过的调侃Neuralstem公司最犀利的段子：Let's say you wanted to test the hypothesis that kissing rubber duckies makes them swim faster. You take 15 rubber duckies to a bridge, give them all a wet sloppy kiss, and toss them into the river. The fifteen ducks eventually reach the next bridge downstream. You label the first seven rubber duckies "affectionate" and the last eight duckies "dispassionate". You then analyze the data and conclude that the affectionate ducks swam significantly faster than the dispassionate ducks. Ergo, there is a large subset of rubber duckies whose swimming performance can be enhanced by kissing. Please explain how the Neuralstem data is any different.
