My bad, I wasn't paying attention: I was too busy commenting to Rishi on the Shamrock Shake-like color of the thing. A fabulously tasty flip -- one that I will have to order again, to check the ingredients of course. For research. For science!

Recipe from Absinthe Cocktails which attributes its creation of this Grasshopper riff to Jackson Cannon:

1 oz Dry Gin
1/2 oz Absinthe
1/2 oz Green Creme de Menthe
1/2 oz Simple Syrup
1/2 oz 50:50 Cream & Half and Half
1 Egg White

Shake once without ice and once with ice. Strain into a cocktail glass. Garnish with either freshly shaved bittersweet chocolate or one dash Mole Bitters.
