Prepare a small tumbler half full of ice then pour some cream soda until you have about half an inch or so left at the top. Then add your Maker's Mark, stir and sip (very important), then add some Jager to taste, I prefer about 1.5 parts of Jager and 1 part bourbon/whiskey because the Jager really won't change the taste very much until you get beyond equal parts with your liquor.

Makes a very nice after dinner drink, and can be strong as well if a night of non-sobriety is required.

You can also substitute any Cola or Root Beer for the Cream Soda. As well as substitute most whiskeys and bourbons for the Maker's Mark.
