Check out this new study in PLOS ONE looking to determine the cause of the "cracking" sound created with distraction at the MCP joint.

"Our results offer direct experimental evidence that joint cracking is the result of cavity inception within synovial fluid rather than collapse of a pre-existing bubble. These observations are consistent with tribonucleation, a known process where opposing surfaces resist separation until a critical point where they separate rapidly resulting in vapor cavities that do not collapse instantaneously."
Also check out the co-author/subject (and Chiropractor) Jerome Fryer showing off his knuckle cracking skills. 
Know you can show patients what is happening in their joints when they "crack".
