Add the tequila, orange-flavoured liqueur, and margarita mix into a cocktail shaker.
Shake, shake, shake, then strain mixture into a large margarita glass with large cubes of ice in it.
To serve, quickly invert the pale ale into the glass, being careful not to spill! Garnish with a lime wedge. As you sip the drink, the beer will gradually fill into the glass, making your drink extra strong!
