why only Corgis are allowed to be gas fitters

Wull. Corgis are little squat thangs, only about half as high as keeshonds, mehbe two-thirds at most. Ya gots be little like that if you're gonna go crawling around under the house where all them gas pipes are. Besides, the cleanup on the keeshond after all that crawling around in the dirt would be a real nightmare. The corgi's got mostly relatively short hair. Ya gots ta look at the big picture, Pfranz. Jeesh!
