The Barber

I'd like to be a barber, and learn to shave and clip,
Calling out, 'Next please! and pocketing my tip.'
All day I'd hear my scissors going, 'Snip, Snip, Snip;'
I'd lather people's faces, and their noses I would grip
While I shaved most carefully along the upper lip.
But I wouldn't be a barber if ...
The razor was to slip.
Would you?
