Three men are sat around the camp fire, knocking back a few whiskeys and chewing the duck fat. The conversation soon turned to their animals as all the men owned dogs.
The first man said "My dog is called Woodworker. I'll show you why I chose the name. Go, Woodworker!" and with that the dog grabbed a log from the fire and began chewing it. Within minutes the dog had chewed out a beautiful figurine.
Not to be outdone, the second man said "Well, my dog is called Stoneworker, watch this." With that he instructed the dog who promptly fetched a rock over and began gnawing away at it. Within half an hour the dog and carved out a beautiful stone figurine.
The third man smiled and said "Well my dog's called Ironworker". He put the poker into the fire and waited until the tip was glowing red hot. "Now" he continued, "all I have to do is touch his arsehole with this and you watch him make a bolt for the door!"
