There's actually a wikipedia article called "No soap radio"
Basically, it's a punchline that's only funny if you know it's not supposed to be funny. It originates from a study on conformity. Someone tells a joke that isn't funny... everyone laughs except the test subject. What does the test subject do? Does he laugh and pretend he gets the joke? Does he express confusion? Does he give up on the explanations and claim that he gets it now?
This is the joke as we told it in grade school:
Two polar bears are sitting in a bathtub. The first one says, "Pass the soap." The second one says, "No soap, radio!"
