Boilermaker
POUR whiskey to brim of shot glass and then manoeuvre shot glass so it is held tight up against the inside base of an upturned Boston glass. Then quickly flip the Boston glass over so that the bourbon is trapped in the now upside-down shot glass. Now pour beer into Boston glass over the whiskey filled shot glass.
