The Kid Stays Out of the Picture - S5-E3
Corrected entry: When Karen enters Grace's apartment, she states she didn't get any sleep at all last night. Then, two minutes later she says "All I know is, when I woke up this morning there was red hair on my pillow and lesbian porn in the VCR."
Correction: That's just a turn of phrase - she may well have dozed off sporadically but to all intents and purposes she got no sleep.
