"Saved by the Bell" alum Dustin Diamond will perform two last comedy shows before he begins serving jail time next month for stabbing a man during a bar fight on Christmas 2014.

Diamond, a standup comedian best known for playing Samuel "Screech" Powers on the popular '90s sitcom, will perform at the Harrisburg Comedy Zone in Pennsylvania on New Year's Eve and Jan. 2. The Jan. 2 show will mark the actor's last performance before he serves four months in jail for charges related to the bar fight.

During an interview with FlipSidePA, Diamond said fans can expect him to relay funny stories about everyday occurrences and bring up a few taboo subjects.

"Whenever something is really gross out there, I bring it up on stage," he said. "And then, if it grosses the audience out, it's great. They leave that night and have nightmares, and I leave completely happy and sleep like a baby."

Diamond added that he is excited to perform in Harrisburg.

"The people in Harrisburg are fantastic," he said. "I'm looking forward to spreading love and comedy joy and meeting new friends."

Both shows at the Harrisburg Comedy Zone begin at 8 p.m., but doors open at 7:30 p.m. Individual tickets are being sold for $20 each. Couples can also buy a $100 package that includes dinner, show tickets, live music and a champagne toast at midnight.

Last week, the 38-year-old comedian appeared in Ozaukee County court and withdrew his appeal of a disorderly conduct conviction. His four-month sentence with work release will start Jan. 15, 2016, according to WISN-TV.

The incident occurred when the famed actor was arrested in Ozaukee County for allegedly stabbing a man with a switchblade during a fight at the Grand Avenue Saloon in Port Washington.

Diamond was then convicted in May of two misdemeanor counts. An Ozaukee County jury also found him guilty of carrying a concealed weapon and disorderly conduct but cleared him of a felony charge of recklessly endangering public safety.
