30 Rock S01 E06 Jack Meets Dennis

"Work can be such a production."

After Liz takes her ex-boyfriend, Dennis, back simply because he asks, Jack takes it upon himself to mentor her as he thinks that she is leading a life of mediocrity. Meanwhile, Tracy gets a tattoo in the face, Jenna gets botox and collagen injections, and Josh is given two black eyes by an angry Liz Taylor.
