Although "Two and a Half Men" is going on a two-week hiatus, the popular comedy series promises to return with a blast of laughs featuring four legendary comedians later on this month.

Comedy icons Carl Reiner, Tim Conway, Steve Lawrence and Garry Marshall will make a guest appearance on an all-new episode of the sitcom on Jan. 30, CBS announced.

During the episode, Reiner will play the role of Marty Pepper, a wealthy man who is dating Alan's mother Evelyn. Marty will propose to her, and Walden and Alan have to find a way to throw him a bachelor party. The other three guest stars will play friends of Marty's who take part in some of the festivities.

"In the episode, multimillionaire Marty Pepper proposes to Evelyn," reads a synopsis released on Wednesday, according to UPI. "In advance of their upcoming nuptials, Walden and Alan throw Marty a bachelor party. Marshall, Conway and Lawrence play Marty's friends who help him celebrate his last days of bachelorhood."

While it will be epic to see all four comedy veterans all in one episode, CarterMatt notes that younger viewers may not have as much of an appreciation for classic comedy or the magnitude of this episode.

"The easy concern here with these guys is that they will be playing a part that is familiar to almost all people over 55 at this point in a comedy: Playing the "'watch a senior say and do filthy things' character," reports CarterMatt. "This is really what helped Betty White rise back to prominence thanks to a few roles that she did, and she even now has a series regular gig on 'Hot in Cleveland.'"

"Two and a Half Men" returns to CBS on Thursday, Jan. 30 at 9:30 p.m. EST.
