Why would you want to stop them?
They are a concealed weapon! The more the merrier. Great for all kinds of situations:
When you ride the train and want to keep that seat to yourself?
When that beautiful girls wants to drain your protein?
When a conversation with your boss has gone on a little too long?
When a staff meeting has gone on a little too long?
When thanksgiving dinner at your in-laws has gone on a little too long?
Silent but deadly man, silent but DEADLY!
