because my job is not just to entertain you, but to educate and teach you, so call me at 1-800-743-CNBC or tweet me @jimcramer." Show medium Cramer is usually standing up with the fisheye lens Steadicam close to his face, while providing stock picks and investing advice. His voice inflection often changes from calm to shouting then back to a calm tone. Cramer also throws various objects around the set. Whenever one of his books is mentioned by a caller, he grabs the book, flashes it, and tosses it to the floor as a plug gag. In addition, he has a panel of oversized red buttons, which activate various sound effects. The online version of the show's sound board is available at cnbc.com. He also has small, plastic bulls and bears which he has incorporated into his shows. After a large gain in the Dow Jones Industrial Average, Cramer, dressed as a chef, chopped off the heads of the bears with a knife and placed them into a pan with onions and tomatoes. He called it a "bear stir-fry" or a "bear souffle". On February 28, 2006, he put his toy bulls through various kitchen appliances. And on May 17, 2006, after a steep plunge of the Dow, Cramer cooked toy bulls through a rotisserie oven. The studio has also featured Cramer bobblehead dolls which utter phrases such as "Are You Ready Skee-Daddy?", callers can receive a free bobblehead upon request. Also, Cramer has National Football League yellow penalty and red coach's challenge flags that he throws whenever he believes a company has behaved unethically (penalty) or when he questions a stock decision (coach's challenge), respectively. He will also throw the flag when a caller unethically uses the national television audience to promote a stock for self-interest. If a caller rambles on about a stock, Cramer will lie down on the floor of the set with a pillow and blanket and act as if he is going to sleep. Other props used include a box of Uncle Ben's Rice with Chair of the Federal Reserve Ben Bernanke's picture, an audio version of Jim Cramer's Real Money, a Louisville Slugger baseball bat, and pink Mad Money pigs. On the May 19, 2006, episode, Cramer had a monkey named Ka-ching make an appearance on the show. Ka-ching wore a CNBC T-shirt, sat in Cramer's chair, pressed the buttons that made sound effects,
