Almost fill a pint glass with ice and pour your liquors (except 151). The Red Bull and orange juice should definatly be poured to taste. Not many people like Red Bull in drinks and prefer more OJ than RB. If your ok with Red Bull it should be poured in equal amount with the OJ. Pour everything into a cocktail shaker and shake well, then pour back into the glass. Pour a small amount of 151 on the top (optional) and do not mix. Serve with a straw.
