The great specialist is sick, lying in the hospital. On a visit to the treating doctor asks:
Doc, when am I on the list?
The Doctor:
In eight or ten days.
A: And before then? I need to go to the factory. In the coming days, the equipment will come, mounting and letting go!
D: And what, will it not work out without you?
C: Yes, they’ll do it, but they don’t need to understand it!
