You're in Russia on "The Amazing Race." For your undergarments you wear:

• Thermal long johns - it's cold there

• Boxers - who can find space for long johns

• A thong - wouldn't want a pesky pantyline ruining my look, that camera's going to film me from behind, I know it

• Nothing - it's cold and if I go commando I'm more likely to find someone to warm my bed
