Last weeks episode of Entourage, HBOs comedy about the
three layabout guys from Queens who are living the Beverley Hills
hignlife when their mate becomes a movie star, answered this

with his calves but finds a plastic surgeon who will give him calf implants.

I dare say you could do the same thing. It's apparently all the rage in Beverly Hills.
