When Neo is getting his info on how to do Ju Jitsu, Tank (or Dozer-not sure) says, "Hey Mikey, I think he likes it!" This is referring to the Life cereal adds with mikey, the kid who hates everything. But, how does Tank know this slogan? He was born on earth and not in the Matrix. Plus, If he doesn't have a plug in his head, he never could have even been in the Matrix!
