A soldier, who was habitually drunk, publicly announced to his company and the surrounding companies that he was swearing off drinking and that all the other soldiers should give up this foul habit also.
The other soldiers would tease him to fall off the wagon by giving him wiskey and get him drunk. Every morning he would be back preaching about the sins of alcohol.
One day his tent mate said he ought to give up preaching about the evils of the jug as he always ends up drunk. With a twinkle in his eye he said-
"What, and give up all that free whiskey?"
