I heard this ad on the radio where they were advertising a machine trimmer, and since the subject content was quite explicit, they used the analogy of front yard.

'Mow the grass till it becomes bare and smooth, it makes your front tree look taller, and mow the back yard as well if you have one'

Heard this in the car, started laughing hysterically.

And shaved or trimmed is my preference. I can't stand body hair.
