Met a lady who had 2 Bouvs

As she tells it, one was smart, the other not so smart (my edit, there are no dumb bouvs).  They had one chair the bouvs were allowed to sleep in.  If the not so smart bouv was in the chair, the smart bouv would run to the door, barking.  The not so smart bouv would then get out of the chair to run to the door, while the smart bouv took over the chair.
