I once (unintentionally) started an argument between two EEs at work by
showing them a schematic for a simple envelope generator. It took one EE (a
30 year old) about half an hour to explain to the other (a 28 year old
recent graduate who was running some very high-end electrical field
simulation software for us) that the DC pulse coming in (the gate signal)
caused the timing cap to charge up. The second EE kept coming back with "but
it's a DC signal and caps block DC." He was absolutely convinced that the
cap would never charge and the circuit did nothing. Neither one of them was
able to answer a question I had about adding a constant-current source to
make linear ramps instead of expo/RC ramps. After the dust settled, I asked
both of them if either one owned a breadboard or had any test equipment at
home. Both said no, in fact, the younger guy asked "what's a 'breadboard'?"
 I kid you not.
 Now both of these guys were doing VERY involved simulations of connectors
and the resulting EFI and magnetic fields with signals in the 5 to 10 GHz
range, and they knew this simulation software backwards and forwards, but...
ANYway, that company folded and I'm working somewhere else now. THAT
shouldn't come as a surprise.
