An old recording of Josh White had a track on it referring to rabbit habits.

Something like:

Jack the Rabbit
Had a bad habit
Ate up the corn
And all the cabbage
But I took him down
To the low low ground
And I cured that fool
Of his bad habit.

(The cut was titled "Don't Lie Buddy")

Or something like that.

Then there was the slogan for Bunny Bread

"Get the rabbit habit"

Yeah Sooz, I wonder at the amount of dubiously useful information. Mental Lint?
