4. Must Have: Hot Tub
From MTV’s "Real World" to BET’s "College Hill" to VH1′s "For the Love of Ray J," there are almost always hot tubs on reality shows. Do reality stars just like to stew in hot water that much? In actuality, the hot tubs are producers’ way of getting stars undressed and encouraging romance. The trend dates back to "Blind Date." Casting directors purposely saught out strippers and models who are normally a bit more comfortable scantilly clad, and the hot tub serves as a great excuse to disrobe.
