Tequila and orange juice, mixed half and half in a glass full of ice.  Pukelicious!
MiniD:  Is a "Brain" anything like a Brain Hemorrhage aka Mushroom Cloud over Baghdad?  Nasty drink.  If I remember correctly, it was some horrible, horrible concoction consisting of Bacardi 151, Jagrmeister, and a couple of other things that created the image of a brain or mushroom cloud suspended in the drink.  Ugh.
