The thing that makes me angry with some of those recordings is when the callers still think that they are talking to a dotty old fellow who they can con (they usually cotton on to the trick in the end). When to my ears Lenny sounds like someone with dementia who needs help and should not under any circumstances be sold to without a legal guardian present, what they seem to take from the situation is "great, I might make my who day's quota on this daft old coot". At that point "but it is my job" really doesn't cut it.
