A super nice patient needs a kidney and dispite Cox's advice, JD goes and talks to the man's son, Murry. Murry doesnt like his dad, but says he'll give him his kidney anways. Tests come back and it turns out the Murry isnt his dads son. JD goes and talks to the Murry and he finally agreess to give him his kidney. This was a great episode and was very funny. Another favorite of mine from Season 4.

JD: He smells like fuel.
Murry: He's a airplane.
