You might think that the easiest thing for James Spader and William Shatner to accomplish on ABC's "Boston Legal" would be those end-of-the-episode scenes where they light up cigars and just shoot the breeze.

Not so, says Shatner, who describes them as "aversion therapy."

After deciding that it might be more fun, visually, to smoke short cigars -- which bring the smoke closer to his face -- Shatner discovered some drawbacks.

"After 20 cigars, I was ill," he says. "A sheen of oily sweat was on my brow" and the makeup people had to put rouge on his face to balance the green.
