This one is so mantastic it will add hair to your chest. It's actually from my days in the U.S. Army.

The Boilermaker (not flaming, but close):

1 beer served in a glass or mug (your choice of beer)
1 shot of whiskey (again, your choice)

Drop the shot of whiskey (shot glass and all) into the beer. If you like, you can throw in a slice of ginger for special effects and added flavor.

Enjoy!
