And when you think about it pronouns can sorta fall into that category too. But I am no linguist, so don't quote me.
I also misread your quote—I’m fairly certain she says “Where one doth not suffice.” Not “Well”.

Noun phrases can include pronouns—or it can just include a noun (usually with a determiner). But noun =/= pronoun. Since we’re discussing “one” being used as a pronoun, I don’t think this sentence demonstrates that if one were to parse it, since it would likely be determined that “one” here serves as a noun. Not a pronoun. But this is obviously beyond the scope of a mere joke.
