A sewer pipe burst and human excreta is flowing from the manholes onto the street.
Plumber and trainee arrive on site, and the plumber immediately dives right into the wastewater.
He resurfaces a minute later and yells:
- 19 mil wrench!
The trainee passes him the wrench. He dives back, resurfaces 30 seconds later:
- Gasket number 6!
Dives back, resurfaces:
- 26 mil wrench!.
Dives. One minute, two minutes. He gets out, shakes off the fæcal sludge, sighs, lights a cig.
- See, young blood? This is how you do it! Watch and learn, or you'll be stuck passing wrenches forever.
