Star of muscial "Scarsdale Surprise!" in "The Summer of George."  Kramer must fire her, for not moving her arms when she tap dances, as the condition to keep his ill-begotten Tony Award.  After becoming aware of her quirk, she is quite aggitated and attacks Kramer.  Also in this episode, Elaine is "catty" with Molly Shannon, who doesn't move her arms while walking, and threatens Elaine.  As Elaine describes her to NYPD on the street, including mimmicing the odd walk, Ms. Welch believes she is being mocked and the two engage in a Cat Fight, much to the delight of the two officers.
