Ozzy Osbourne and Justin Bieber Star in Best Buy's Super Bowl Commercial (VIDEO)

Some people call it Super Bowl Sunday, but for just as many people it's become Super Commercials Sunday. Advertisers pulled out all the shots for their expensive 'Super Bowl XLV' (Sun., 6:30PM ET on FOX) spots, which usually includes flashy special effects, huge guest stars, and a healthy does of weirdness.

Best Buy addressed the speed at which technology advances by comparing it to the world of pop culture. Ozzy Osbourne represented the "old" pop culture phenomenon, dating back to his popular MTV reality series, while Justin Bieber represented the new.

The spot was framed like it's a commercial shoot for 4G technology, but as they're shooting it escalates to 5G and finally 6G. Osbourne is on board for the start of it, but as he gets more and more confused, Bieber steps in.

"I'll take it from here," he says, and the shoot moves on.

In a fun little bit at the end, Ozzy and Sharon Osbourne question what 6G is and even what a "Bieber" is.

We almost didn't recognize Bieber in his "middle-aged man" make-up standing behind the two. He had a little fun at his own expense.

"What's a Bieber?" Ozzy asked.

"I don't know," the "middle-aged" Bieber behind him said. "Kind of looks like a girl."
