DEREK: "So, when did this problem begin?"
STEVE: "Well, I had an erection last night and woke up with one this morning."
MIRANDA: "Umm, Dr. Shepherd, if you don't need me, the other Dr. Shepherd needs a consult on one of the quints."
DEREK: "Yeah, no we're fine. So when did you last ejaculate?"
STEVE: "I'm not sure. Meredith?"
CRISTINA: [leaves, tries not to laugh] "Oh, I'm... I'm gonna go with Dr. Bailey."
STEVE: "Meredith, what time did we, uh...you know."
DEREK: [smiles] "Yes, Meredith. What time did you two?"
