One comment I've heard levelled at talkers is " The last time a saw a mouth that big, it had a hook in it".

A word of caution is be sure that you are in a "safe" environment. Recently I asked then had to instruct a member of the audience to get off my playing stool and to leave my guitar alone during the interval. His response was to suggest that we settled the issue in the car-park of the inn!!

Sometimes, absolute politeness is the only wayto survive!!
