Rich, do you clip your fingernails during consultations? My shrink used to clip his nails and say "uh huh" a lot. I always wondered if that was characteristic of the breed - like red hair on Irish Setters and such. My daughter used to call them Irish Shedders when she was a tyke. Hmmm...maybe she was right! But I digress....... 
I find it much more useful to clip my toenails, and engage in other forms of personal grooming (e.g., candling ear wax, trimming nose hair, etc.) to give your client that feeling of "intimacy" that he/she so desires in a shrink.
