Rusty nail (Scotch and Drambuie), velvet hammer (I've seen some variations of this recipe but I've seen equal parts Cointreau orange liqueur, coffee liqueur, and half and half as well as variations with vanilla ice cream and creme de cacao and with cognac and vodka. Not all the liquor in the same drink, of course, because that's a lot of alcohol for one drink if so), and boilermaker (based on location. In America, it's usually a beer with a shot of whiskey or whiskey chased by bear. In Britain, it's a mix of brown and mild ale. In Scotland, it's half a pint of beer with whiskey) all come to mind off the top of my head.
