A party of visitors were being shown round a lunatic asylum．They came across one individual in the grounds，with wild eyes，dishevelled hair，feverishly endeavouring to catchflies and keep them in his pocket．
His was a sad case，said the attendant．Whilst he was at the war his wife abandoned his home and ran off with another man．
Terrible，said a visitor．
Presently they came to a padded cell，in which could be heard a raging as of a wild beast．
That's the other man，said the attendant．
