Dustin Diamond 1st Post-Jail Interview With Saved By The Bell Cast-Mate

(Extra) It was a powerful "Saved by the Bell" reunion as Dustin Diamond sat down with "Extra's" Mario Lopez for his first interview since being released from Ozaukee County Jail in Wisconsin. Dustin was found guilty of disorderly conduct and carrying a concealed weapon after a barroom brawl in 2014.

In the wide-ranging, exclusive interview, Dustin spoke in detail for the first time about the altercation that landed him behind bars, opens up about his sex tape, reveals the truth about his book, "Behind the Bell," and tells Mario what's next for him.

Dustin tells Mario he and fianc�e Amanda Schutz were out celebrating Christmas at the Grand Avenue Saloon in Port Washington, Wisconsin when a group of people confronted them asking for photos. Things soon went out of control.

"One of the girl's friends [Amanda] was talking to sucker-punched my fianc�e� she leaned back to me and her face was covered in blood." When a male got involved grabbing Amanda by the hair, Dustin needed to protect her and ended up getting tackled by a male, "I opened my pocket knife and said, 'Let my wife go immediately,' which worked."

Setting the record straight on allegations he actually stabbed 25-year-old Casey Smett, Diamond said, "I had my pocket knife like this... and the blade was right here and the guy came from around me and grabbed my throat, and so he nicked his arm on the tip of it -- it was a Band-Aid, the most expensive Band-Aid I've ever bought."

The 39-year-old was sentenced to four months in jail, getting out after three for working as a janitor. He told Mario that it's not like what you see on TV. "It's pretty daunting, it's pretty scary going into that environment. I found that as long as you follow the rules and stay with the system, it works. You can get in and out unscathed."
