It's J.D.'s last day of teaching and the students all submitted their teacher evaluations.  Even though J.D. is the top-rated teacher, he gets one bad evaluation.  He's determined to find out who it is and teams up with Turk as the interractial Hardy boys and they discover a path of clues that lead them to Dr. Kelso's shag pad.  Damn, a dead end.  Dr. Cox eventually reveals it's him that wrote the evaluation, he has one last thing to teach J.D.  He does not need other people's approval and doesn't need to keep babying the students.  It's medical school, not kindergarten.

Meanwhile, Lucy is unable to draw blood from anyone except J.D.  He agrees to let her use him during her exam when she proves unable to draw from Cole.  To let Lucy grow and after Cox's speech, J.D. doesn't show up to her test and she draws blood successful from Cox.

Oh and Sunny is back and wants to double date with Denise and Drew.  Drew says no and Denise quickly pretends like she didn't want to either.  Cox convinces her she's losing the power in the relationship so she makes him go and ditches him during the date.  She explains to him they're in a relationship because she said so.
