Random Rhyme Scheme Generator

A quick-and-dirty app to generate a random stanza schema between 4 and 14 lines long. The stanza is guaranteed to have no unrhymed lines (abxb) and not to be monorhymed (aaaa).

The code really is smelly. I might sanitize it later, but probably not.

Definitions

Random

Every option is equally weighted. For instance, a 14-line stanza is as likely to be generated as a 4-line, or an 8-line.

Weighted Random

Middle values are more common. A 9-line stanza is more likely than a 6-line stanza, and 4 or 14 lines are least likely of all.
