ABC has announced the penultimate episode of The Middle's current season, which will air Wednesday, May 16. Chris Kattan and Brian Doyle-Murray return as Bob Weaver and Mr. Ehlert, respectively, in the episode.

"The Telling" - It seems like Frankie truly has eyes in the back of her head when she busts both Sue and Axl for making some bad choices that they thought no one would ever find out about. But when it turns out that she's using Brick to be her snitch, Mike is completely against it. Meanwhile, Axl's weekend getaway to the lake is in peril when Sue discovers him sneaking into the house in the middle of the night and coerces him into doing whatever she commands -- otherwise she will tattle on him; and when Frankie is stuck at work, Mike is forced to attend Parent Day at Brick's school, on "The Middle," WEDNESDAY, MAY 16 (8:00-8:30 p.m., ET) on the ABC Television Network.

The Middle has not yet been renewed for a fourth season, but the show is widely expected to return next year. ABC so far seems reticent to announce any early renewals, so we might not get the official word until ABC's upfront presentation on Tuesday, May 15.
