Nick Viall revealed some pretty graphic details to Andy Cohen on Thursday night about his bad "Bachelor" behavior.
Playing a round of "Bachelor Dish in the Dark: Never Have I Ever Edition," Viall was asked about bodily functions, avoiding the kisses of foul-breathed contestants and becoming aroused during group dates.
The "Bachelor" star was given a flashlight and sat in semi-darkness as Cohen told Viall to shine the light in his face should he be "guilty" of any of Cohen's allegations.
