During second episode of "Being Bobby Brown", Whitney and Bobby are talking about colon cleansing, when Bobby says to her, "I've seen worse," he says. "I've had to dig a dookie bubble out of your butt."

Bobby even admits that once when "her turd was too big" for her to excrete, he had to pull it out with his fingers.
