How does one tell a pomegranate from a persimmon?

The last stock tip I received in the pub was to buy frog bellies.

Sure, it was up and down for a while but it suddenly sank.

Left me feeling green around the gills, so to speak.

One case in medical literature from 2004 revealed a 51-year old patient who had eaten a kilogram (2.2 pounds) of unpeeled persimmons each day for 40 years.[19][20] Surgery is sometimes employed, but Coca-Cola has also been successfully used to chemically shrink or eliminate persimmon-related bezoars.[21]
