A Wisconsin 4-year-old boy LOVES toilets, and is the star of this video produced by fixture-maker Kohler.

Dustin Kruse first started showing an interest in toilets when he was only 18-months-old, and his mom 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.

I guess with a plethora of other things he could be obsessed with, this is relatively harmless.

I'm fascinated with his fascination.
