I think that with all techie humour, we should start from the idea that all techie salesmen lie. Thus, the techie folk have to deliver the lies that the salesman has promised.
Just a quick observation from Christmas parties.
1. SAP massively over-promise to Lease Plan in Aus/NZ. Millions spent by Leaseplan, zero product so far.
2. Astra Zeneca CIO and team fired by Astra Zeneca CEO. They tried to import their (OK) IBM contract in USA to rest of world. Failed.
3. CSC. Told one story to Government in UK. Told a very different story to shareholders via SEC. Some half-awake journo spotted that one of these stories must be a "terminological Inexactitude"
