McLovin’s fake ID from Superbad turned 40-years-old on Wednesday. That is to say the birthdate on the Hawaii driver’s license he used to buy booze in the 2007 comedy was: 06/03/1981. This is not to be confused with the birthday of the actor who played McLovin, Christopher Mintz-Plasse. He’s 31.

Those still left wondering what that mix of words above means can watch the attached clip and freeze it around the 1:11 mark. Should explain everything.
