'The Office': Stephen Collins, Dee Wallace playing Andy's parents

Ever wonder how Andy Bernard got to be the way he is? You'll get part of that answer on "The Office" this season, when we meet the Nard-Dog's parents.

Stephen Collins ("7th Heaven," "No Ordinary Family") and Dee Wallace ("ET," "Sons & Daughters") will guest-star as Andy's (Ed Helms) folks in an episode this fall, EW reports. Collins tweeted about his guest spot Tuesday (Aug. 16), calling the cast a "ridiculously fun & talented group" and noting that in 1989 he worked with Rainn Wilson on Wilson's first professional acting job.

From what we know about Andy's pre-Dunder Mifflin life, Mr. and Mrs. Bernard are fairly wealthy, and Dad's connections at Cornell are what got Andy admitted there. We're also guessing that they're either A) rather disappointed with Andy's current station in life or B) so coddling that they think he's doing super-awesome.

A date hasn't been set for the Collins-Wallace episode, but if they're filming now it should be on the air in the first month or two of the season.
