Radio interferometers are complex -- and above all counter-intuitive -- instruments, and we are constantly pushing the envelope of their performance with increasingly sophisticated science experiments. The combination of these two circumstances can produce some real surprises -- most of them of the unpleasant variety. I will present some examples of surprising observational limitations, both in real-world and simulated data (DDEs, calibration ghosts, sidelobe confusion, calibration noise) and discuss their possible impact on future radio surveys.
