Synopsis of their skit:
An interchange between a therapist and her patient (Esh). She has trouble getting words correct and he ends up by hugging her as she unloads on him. She keeps wanting him to fill out personal ads even though he is in a relationship with another guy. Wonderful interchanges and they did a great job.
The full play (has been played by John Lithgow and Dianne Weist) can be found at:
