"Thud" -- the parachutist's four-letter word. That and "Oops!"

"What a rush!" Where have I heard those words before? Rappelling without a harness or safety line? Climbing a 270 degree slope in the rain? Flying a helicopter through heavy ground fire? Jumping a snowmobile across Hell's Canyon? "Just hold my beer and watch this!" "Them drops of oil on the outside just means the dynamite's in good shape!" "Hell, it ain't loaded!" "If it was sharp would I do THIS with it?"
