Dustin Diamond may wish he was trapped in a Bayside High School locker again come mid-January.

On Jan. 15, the former "Saved By The Bell" star will begin serving a four-month jail sentence for stabbing a man last Christmas day in a Wisconsin bar.

He will be able to leave the facility for work release.

Dustin appeared before the Ozaukee County court on Dec. 16 to receive the start date of his jail sentence.

Last June, Dustin was convicted of carrying a concealed weapon and disorderly conduct, both misdemeanors. He was originally charged with a felony, but he was cleared of that.

Authorities said Dustin's girlfriend got into an altercation with another woman who was antagonizing the couple at the bar on Dec. 25, 2014. It eventually turned physical and Dustin began defending his girlfriend, which is when he pulled out a switchblade knife.

A police report said the actor "stabbed another male patron and left the bar in a white SUV with his 27-year-old girlfriend. Officers quickly located the suspecta and their vehicle, and took both into custody." The statement added, "Further investigation revealed the suspects were in the Grand Ave Saloon where an altercation took placeā€¦ [and] escalated to the point where a victim was stabbed by the 37-year-old suspect. The knife was recovered in his vehicle."

The victim suffered non-life threatening injuries.

Dustin, of course, rose to fame in the 1990s and he played the nerdy "Screech Powers" on "Saved By The Bell." Since then, his life has had a lot of up and downs. In 2012 he released a sex tape but later claimed that he used a body double. Since "Bell," he also appeared in "Celebrity Fit Club" and "Celebrity Boxing."

Sounds like the jail commissary will be his new version of "The Max."
