In the blood drive van, Dwight flexes his arm to pop a vein out for the nurse. He THs, "I've trained my major blood vessels to retract into my body on command. Also, I can retract my penis up into itself." The camera stays on his face just a little too long, until he gives a little nod of satisfaction. EW!
Michael enters the bloodmobile, where another cute brunette donor is already hooked up. She claims that she's too nervous to talk, while talking a lot, which Michael points out for her. Once his own vein is tapped, he decides to fill the nonexistent conversational gap by firing off a series of bad jokes like "Human juice box," "Hawaiian blood punch" and "Type O-cean Spray." Well, look who's bringing his A-game.
Up in the office, Phyllis invites the banished Pam and Jim to lunch with her and Bob Vance of Vance Refrigeration. Jim claims he has a busy afternoon: "Those mines aren't going to sweep themselves." Which is their way of accepting.
Michael makes the mistake of looking at his blood bag, and asks his neighbor to distract him. She tries to join him in some banter, and adds that he's cute, so clearly the blood loss is having an effect on her. Michael is done first, for some reason, and as the nurse disconnects him, he confides, "I was so nervous about this, I don't think I ate for three days." Right on cue, he passes out.
