Pour the desired amount of Jagermeister into a durable shot glass as short as possible. mix the Cola and ginger beer together in a pint glass. Bomb the shot into the pint glass and chug. Note: Serve quickly before the initial strong carbonation of the ginger beer fades. Additionally make sure the base of your pint glass is thick as a quickly bombed in shot glass can blast right through the base of some pint glasses. Great for a laugh but terrible for business.
