Continuity: In the coffee house, when Ross and Joey are having a fight about Joey's proposal to Rachel, Ross makes "air quotes" and Joey says he doesn't know what they mean. But in "The One with the Secret Closet", Joey uses them correctly: Joey asks if Chandler has a bobby-pin to unlock the closet door. Chandler says, "Maybe Monica has a bobby-pin", to which Joey responds, "Sure... (air quotes) 'Monica'..." Joey also understands what they mean in "The One with Rachel's Date". When Ross talks about Rachel's date being with an "actor", Joey says, "Hey... I'm an (air quotes) 'actor', too".
