Here is the quote:
A Japanese freighter had been torpedoed during WWII and it's at the bottom of Tokyo Harbor with a large hole in her hull. A team of engineers was called together to solve the problem of raising the wounded vessel to the surface. One of the engineers tackling this puzzle said he remembered seeing a Donald Duck cartoon when he was a boy where there was a boat at the bottom of the ocean with a hole in its hull, and they injected it with ping-pong balls and it floated up. The skeptical group laughed, but one of the experts was willing to give it a try. Of course, where in the world would you find twenty million ping-pong balls but in Tokyo? It turned out to be the perfect solution. The balls were injected into the hull and it floated to the surface.
Myth-busters say plausible, but did this happen with the Japanese ship?
I know proving negative is impossible, but may be it's a positive I failed to google?
