Griffin entertains at Walter Reed

“Kathy Griffin: My Life on the D-List” (9 p.m., Bravo) wraps up its fourth season with a visit to Walter Reed Army Medical Center to entertain wounded and recovering veterans of the wars in Iraq and Afghanistan.

How does a comic best known for foul language, a large gay audience and humor marinated in the minutia of pop-culture trivia prepare for an audience of recovering soldiers, families and officers? Before her show, Griffin goes through her patented routine, conferring with “Team Griffin,” consisting of her assistants and dog-walkers as well as her 80-something mother and her ever-present glass of wine.

The episode gathers strength when she visits her potential audience – the amputees, wounded men and women and their spouses and children. Griffin is clearly moved by the dark humor of the men who seem to laugh off a below-the-knee amputation as a minor setback. And she’s struck by the strength and stoicism of their wives. Many of the veterans and spouses have yet to reach their 20th birthday. At her best, Griffin always puts her show-biz world in its proper perspective. “When I was that age,” Griffin interjects, “I was temping and auditioning for ‘Fresh Prince of Bel Air.”‘

As usual, Griffin’s performance experiences some wobbly moments before connecting to an audience consisting of families, children and four chaplains. With typical self-deprecation, Griffin observes, “I was performing for people in wheelchairs and amputees, and they still walked out.”

“Kathy Griffin: My Life on the D-List” has been nominated for an Emmy award in the Outstanding Reality Program category for the third consecutive year. She won last year, and Kathy doesn’t let anybody forget it.
