An immunologist and a cardiologist are kidnapped.

The kidnappers threaten to shoot both but promise that whoever has made the greater contribution to humanity will be shot the next day..

The cardiologist says, "Well, I've identified drugs that have saved the lives of millions of people." 

Impressed, the kidnappers turn to the immunologist. "What have you done?" they ask.

The immunologist says, "The thing is, the immune system is very complicated…"

And the cardiologist says, "Shoot me first."
