Mouse then asks how many times how many times he has tossed his cookies (or "threw up") and the Count says he will count the times. The Count then counts, "One, one puke, two, two pukes -- ha ha ha -- three...", but before the Count can finish, Mouse swings at him and pins him to the wall. He then says, "If you don't can it, you'll be counting the number of stitches I put in your face!", and the Count nervously responds, "Ah yes." One of the doctors suggests that Cookie is barfing because he eats 700 cookies a day (bags of cookies are seen all over the room). Mouse disagrees with her. Later, a doctor says Cookie Monster is getting worse and his x-rays are baffling. She then holds up an x-ray of him that shows he has a hand inside of him. Mouse lifts up Cookie Monster's bedsheet and a puppeteer is under the bed (the puppeteer looks like George Clooney). The other doctor says she still believes it's the cookies he's eaten. Cookie Monster then remarks "Me like cookies!" Mouse claims that he is lying and will prove it by inducing him to vomit. Mouse then shows Cookie a picture of Spencer Pratt. Cookie Monster groans and says he's so sick of Spencer and loudly vomits several times. The Count begins counting how many times he pukes, until Cookie Monster barfs right into his mouth. The Count swallows it and continues counting. Mouse finds broccoli in the mess and figures out that Cookie Monster has been eating vegetables and his body is rejecting them. Cookie admits it and announces that he has been eating vegetables without anyone knowing. The Count then hugs him and Cookie smiles.
