Well, once I was making a peanut butter sandwich. Next ad I saw on my phone was for an organic brand of peanut butter. I never said or searched for anything related to that. So my theory is that the phone has an undisclosed odor sensor in it that is sending back data. My point being, that if you have a large enough data set then you can find all kinds of coincidences within that set. I.e., I'm sure you've heard of the comparisons between Lincoln and Kennedy (i.e., Lincoln was killed in the Ford theater, and Kennedy was killed in a Ford). This is also known as the Texas Sharpshooter's Fallacy.
