In 2007, Oklahoma made watermelon its official state vegetable.
Yes, you read that right: on April 17, 2007, the Oklahoma State Senate passed a bill declaring that not only is watermelon a vegetable (related to cucumbers, they said), it's also the state's official vegetable. (Source)
Other states have official vegetables are:
Arkansas - South Arkansas vine ripe tomato
Georgia - Vidalia sweet onion
Idaho - potato (what else?)
Louisiana - sweet potato
New Mexico - chile and pinto bean
North Carolina - sweet potato
Texas - sweet onion
Utah - Spanish sweet onion
Washington - Walla Walla sweet onion
Webster defines a vegetable as "1 a: of, relating to, constituting, or growing like plants b: consisting of plants".

Fruits are defined as "1 a: a product of plant growth (as grain, vegetables, or cotton) b (1): the usually edible reproductive body of a seed plant; especially : one having a sweet pulp associated with the seed "
So all fruits are also vegetables, but not all vegetables are fruits. So the Oklahomans aren't crazy, they just read the dictionary and decide to fuck with all the people who consider them nothing more than flyover country.
I'm a current OK resident (I work for an oil company) but I'm not from here.
A berry is a small, pulpy fruit with a pit(i.e. seed) in the center. Therefore, a grape is a berry, and a strawberry is not. Melons are not berries, they're not small.
Furthermore, the cucumber is a member of the melon family, it's just elongated. A cucumber is a fruit because fruits have seeds, vegetables do not. A watermelon is NOT a vegetable. (Even seedless ones have smallish seeds.) A tomato is a fruit (it has seeds).
The second webster's definition is the abstract concept, i.e. the fruits of your labor, fruits of the harvest.
The fruit of a plant is the matured pistil of the flower.
we really need to educate our leaders
