ABC has announced the third season finale of The Middle, which will air Wednesday, May 23. Norm Macdonald, John Cullum and Chris Kattan reprise their roles as Rusty, Big Mike and Bob in the episode.

"The Wedding" - Frankie and Mike are surprised to receive an invitation to Mike's brother Rusty's (Norm Macdonald) fast approaching wedding. But their surprise turns to panic when they discover that he has listed the Heck house as the site of the ceremony. Meanwhile, Axl and his friends decide to become their own bosses and set out to form their own company to garner summer jobs, and Brick is upset with Mike when he finally accepts an invitation to a fellow student's party but is not allowed to go because it falls on the same day as The Wedding, on the Season Finale of "The Middle," WEDNESDAY, MAY 23 (8:00-8:30 p.m., ET) on the ABC Television Network.

You can find more information about the episode in our Episode Guide. With the current season now coming to an end, we obviously look to the future of the show. Right now The Middle has not been officially renewed for a fourth season, but the show is widely expected to return. ABC has held back from renewing any of its shows so far, so we may have to wait until their upfront presentation on Tuesday, May 15 before we know for definite.
