Good morning Bagram as Robin Williams zooms in

Unfettered by domestic prudery, Williams dished out plenty of expletives and sexual innuendo, but inverting the norms of US television, his Hollywood publicists were insistent media cameras should show no guns in the same frame as the star.

Williams made sure that most of his routine was more suitable for the barrackroom than family television viewing. But from the moment he introduced himself with an earsplitting ‘‘Goooodmoorning Bagraaaaam!,’’ recalling his role as a military radio presenter in the movie Goodmorning Vietnam, he was a huge hit with the hundreds of male and female troops in the audience.

‘‘Good luck with those shots fellas’’ he quipped to the cameras after using a plastic mineral water bottle to demonstrate the supposed effects of Viagra, adding to a female soldier: ‘‘I’m sorry for spraying you girl — don’t go Oprah on me.’’

He had the troops in stitches with a pun on the supposed intestinal effects of ‘‘Meals Ready to Eat,’’ as well as references to the ban on alcohol at US bases in Afghanistan and sexual frustrations in what is a strict Muslim state.

Williams laughed off the dangers of Afghanistan, joking that it was impossible to complete a round of golf because the 10th hole was mined.

‘‘A lovely flight in thank you,’’ he said. ‘‘I love spiralling in. Nothing like that to make your colon say ‘fire in the hole!’’’
