Zach (one of the house hunks) earned a punishment for losing a competition and chose Rachel (the returning player who "goo'd" last week, a former Vegas waitress) as his "partner in crime"
Every 10 minutes, they try to "steal" a money bag from the "vault". If it has "counterfeit" money (blank paper), they have to face forward and get hit with a jet of blue paint from the "dye pack", take a "mug shot" and "go to jail" (sit outside while wet) to wait for another round - again and again until they find the four bags of "BB money" out of the 40-60 bags available. So six TV minutes (and half a day of filming) with repeated, often slow motion face shots of blue paint, followed by a posed photo with goggles removed while the paint is still wet..
