Similarly, the Italian drink called the Bocce Ball is pretty good:

Amaretto
OJ
Ice
a splash of Club Soda

Play around with the proportions a bit to find that happy point where it doesn't taste like amaretto or orange juice, but just warm, filtered sunlight.  I usually add some vodka to stiffen it a bit, but beware of crappy vodka that makes it taste like it came out of a gas tank.
