A Minnesota man is on thin ice after picking up a DUI while on the job - an environment that has him driving around kids and families on a slick surface to begin with.

FOX News Radio's Chris Hoenig has details:

Joel Buss allegedly had a few cold ones before hopping behind the wheel at the Hayes Arena in Apple Valley.

(Song) "Yeah, I wanna drive the Zamboni..."

Buss drives the ice-cleaning Zamboni at the skating rink.  It was parents who first alerted authorities to his impairment.

(Johnson) "Coaches noticed he was off the mark by quite a ways and bumping into the boards."

...Apple Valley Recreation Director Randy Johnson.  Authorities say Buss stumbled off the machine and his breath wreaked of alcohol.  Turns out it's not his first go-round: Buss has three prior DUI convictions dating back to 1999.
