Robert Rankin has proposed in his books that
Sprouts are a demonic race. Anyone who has seen the obligatory sprout lurking on the edge of their plate at christmas time will not doubt the menace of these green spheroids.

There was a talkative time sprout named Barry in Elvis' head.
And who would doubt the word of the Rankin?
