Can anyone advise how many ounces of ice constitutes a "scoop"?

In addition to the lovely drinks and duly worthy commemorations above, may I suggest also raising a glass to four blokes from Manchester, who on this day made a bit of a mark on the music scene with their major television debut. Perhaps toast with a This Charming Cocktail, which is slightly, only slightly less interesting than a sardine.

Green Chartreuse has been nearly impossible to find the last few years in Oregon, though I did find a bottle through sheer dumb luck. But now I'm afraid to use it lest I run out, which is an absurd condition. If only the Carthusian Monks could increase their production capacity just a wee bit.

Love the Angostura on the nose with every sip.

I love this drink and have enjoyed it many times – some directly from the hand of Mr. Morgenthaler. Just recently, however, I discovered I was out of Bourbon, so I decided to sub in Johnny Walker Black. Still works! And thus, a new drink ‘round my house was born: The Urbane Restorative – an homage to the late Christopher Hitchens, whose love of “Mr. Walker’s Amber Restorative” was no secret. And in proper tribute, I then proceeded to take on all comers in a spirited defense of whiskey sours.

I believe you meant "Silver" Bullet. And re Bystander Effect: and partly (or mostly) because each concluded that other people were already doing something about it.
Wonderful Scofflaw by the way.
