I will discuss some of the techniques currently in use for the direct calibration of the response of dark matter detectors. This will include both nuclear recoil and electron recoil events. I will focus on the most innovative and entertaining techniques that have been developed which have allowed the accurate measurement of the response of detectors to dark matter and to a range of backgrounds. I will also survey the many pitfalls to developing this understanding which have sometimes lead to the premature discovery of dark matter signals.
