 CONT: In this episode Joey and Alex are watching a commercial  advertising Joeys appearance on "The Ellen Degeneres Show" the next  day in which we see Joey walking across the stage and hugging Ellen.  The next day when Joey goes to tape the appearance on Ellen, she  says "Nice to meet you" and he replies, "Its nice to meet you too"  implying that theyve never met. But we had just seen them interact  in the TV commercial, showing that they had in fact met before.
