The Big Doors are the most vital part of the set; they're the ones that house the prizes offered in most pricing games (such as Most Expensive, Danger Price, Swap Meet, One Right Price, and Switch?) and the Showcases. Sometimes the doors house IUFBs (items up for bids; the common name for One Bid prizes). Furthermore, the middle doors double as an entrance for the host to go through after the first contestants were called to "Come on Down" (the 1994 Davidson version had Doug come through the doors after the intro). Occasionally, games such as 3 Strikes, Golden Road, Pocket ¢hange, and Plinko would take place in front of the middle doors and covered by either curtains, the big drape, or The Giant Price Tag; if this happens, the host will usually enter through the audience, so as to not give away the game.
Drew made the first of his three audience entrances on June 23, 2008 (#4391K). He made two more audience entrances on February 17, 2015 (#7012K), as part of #UDecide Week and September 23, 2015 (#7213K), as part of Decades Week.
