The wierd questions I was compelled to look up today instead of working:

A homonym is a word that is spelled and pronounced the same but has different meanings, and a homophone is a word that is prounounced the same but is spelled differently and has a different meaning.

i is the mathmatical terminology for the square route of negative 1. -i is i^3

Alt+8253 is the way to type an interobang in the few fonts that support it

The only things classified as vegetables are leaves, roots, and tubers. Anything that includes the seeds is a fruit, including peppers, cucumbers, pumpkins, and tomatos

Ah-ha!
Those are all absoloutes, apart from the last one, which isn't :P
Although right in some ways, “fruits” are still vegetable matter, and the classification of “fruits” and vegetables wasn't entirely scientific: it was done as part of early international trade agreements… So they could decide on taxes, import duties, tarrifs, customs and all that.

well one must understand common nomenclature as well.

as a cook if someone orderd a dish without vegetables I knew not to include peppers, or mushrooms, even though one is a fruit and one is a fungus
