Jerry Garcia and Palmolive dish soap

I just heard a story (possibly apocryphal?) that Jerry Garcia refused to wash the dishes when he was living in the famous communal Grateful Dead house on 710 Ashbury, which is roughly a three-and-a-half-minute walk from where I live. According to the story, Garcia made a case that the Palmolive dish soap would soften the calluses on his fingers, therefore harming his guitar playing. Recently, I tried a similar argument in my household to get out of doing the dishes. She isn't buying it, though.
