Stiller Disturbed By Dad's Dog Training

BEN STILLER is still scarred by his father's dog training methods - because they involved suppositories.

The funnyman has reluctantly revealed his dad, beloved comic Jerry Stiller, had an odd way of toilet training the family pet.

He tells Playboy magazine, "I don't think the practice is widely accepted. It's probably the most politically incorrect training method in history.

"The suppositories were supposed to stimulate the dog to go to the bathroom.

"My dad had to administer them - on the street... Jesus, now that I think of it, it's crazy. I can't imagine having to do it. God, that's a horrible image."

Stiller and his wife Christine Taylor have two dogs and a puppy.
