Great Interview Question

While meeting with the folks at George Mark Children's House last week the topic of hiring came up. They suggested a great interview question. It is definitely applicable to small to mid-sized social service non-profits but I think it is good assesment question regardless of the size of your business or industry it is in. Ask all candidates, regardless of the type or level of job they are interviewing for, if necessary would they be willing to do the dishes and clean the facility? Would you?
