The 20th anniversary of MADtv will be celebrated on TheCW with a one-hour reunion special next month.

MADtv originally ran for 14 seasons, from 1995 to 2009, and helped introduce several comedy stars still working in Hollywood. The show’s most famous alumni include Jordan Peele, Keegan Michael-Key, Ie Barinholtz, Alex Borstein, Orlando Jones and Simon Helberg.

The former stars who have signed up to make appearances in the special are Barinholtz, Borstein, Michael-Key, Mo Collins, Crista Flanagan, Anjelah Johnson, Nicole Randall Johnson, Phil LaMarr, Artie Lange, Bobby Lee, Michael McDonald, Arden Myrin, Nicole Parker, Eric Price, Will Sasso, Aries Spears, Nicole Sullivan, Stephnie Weir and Debra Wilson. The stars are reuniting for an awards show to honor MADtv, but it breaks into chaos.

The special will be a combination of clips from the show’s funniest sketches and new material. In addition, The CW will make 75 of the series’ best episodes available to stream on CW Seed on Jan. 5.

MADtv 20th Anniversary Special will air on Tuesday, Jan. 12 at 8 p.m.

MADtv won five Emmys during its run and originally aired on Fox.
