Mickey Mouse milk ad is a relic of olde worlde naiveté (or it's just rude):

This undated old Grad Rapids Milk ad features a bit of dialogue from Minnie and Mickey Mouse that either contains a rude double-entendre or is a relic of an era of unbelievable naiveté. Either way: snigger snigger snigger.
