What's a Paw Paw??

In listening to an NPR story this week on a tropical-like fruit growing in the Washington DC area I was fascinated to learn more about this mango-like fruit.  They found the paw paw along the Potomac River. Some of what I learned on the internet:

The pawpaw is the largest edible fruit native to America. Individual fruits weigh 5 to 16 ounces and are 3 to 6 inches in length. The larger sizes will appear plump, similar to the mango. The fruit usually has 10 to 14 seeds in two rows. The brownish to blackish seeds are shaped like lima beans, with a length of 1/2 to 1-1/2 inches. Pawpaw fruits often occur as clusters of up to nine individual fruits. The ripe fruit is soft and thin skinned

Pawpaw fruit ripens during a four-week period between mid August and into October, depending on various factors. When ripe, it is soft and yields easily to a gentle squeeze, and has a pronounced perfumed fragrance. The skin of the green fruit usually lightens in color as it ripens and often develops blackish splotches which do not affect the flavor or edibility. The yellow flesh is custard like and highly nutritious. The best fruit has a complex, tropical flavor unlike any other temperate zone fruit. At present, the primary use of pawpaws is for fresh eating out of hand. The ripe fruit is very perishable with a shelf life of 2 or 3 days, but will keep up to 3 weeks if it is refrigerated at 40° - 45° F.

Has anyone ever eaten or purchased one?
