A 4-year-old from New Berlin fascinated by toilets is the star of a video produced by fixture-maker Kohler that has more than 100,000 hits on YouTube. Dustin Kruse, who first started showing an interest in toilets when he was only 18 months old, came to the attention of Kohler when he visited the company's Design Center in Kohler with parents Jim and Michele Kruse and his mother later sent the company a letter asking about a possible demo model of the boy's favorite toilet, a $380 dual-flush toilet. The company decided instead to send the family a free toilet with a company plumber to ensure it was properly installed.
