This is actually for a friend of mine...
My friend works for a major defense contractor.
Boss to friend: Do you have any idea why your software wont work with our widget at -120 celcius?
Firend to boss: Well, I wrote the software in C, and its only rated down to -50 Celcius. To go to -120C i would have to use C++.
The boss apologized for being so silly after realizing his error.
