Katie (Soleil Moon Frye): An extremely (and constantly) energetic girl whom Joey dates in "The One with the Girl Who Hits Joey". As the episode name suggests, she's a woman whose play-punches are all-too-hard. A seemingly nice person nonetheless, she appears to like Joey a lot, apparently bemused but also highly amused by wacky antics from him such as "breadstick fangs" but she's so energetic that whenever she playfully punches him on the arm she accidentally hurts him, but seems to be oblivious to this. When Joey actually tells her, she thinks he is merely making good-natured fun of her small size. Joey eventually decides he wants to break up with her as a result, but worries about hard she will hit him if he in the process of doing so upsets her, but Rachel gives him an easy way out when she retaliates in anger after Katie playfully punches her and accidentally hurts her also by kicking Katie's ankle, and when Joey refuses to stick up for Katie upon witnessing this she, as he had hoped, breaks up with him and leaves. She is never seen again afterwards.
