Dirty Job's fourth-season premiere episode will find Rowe as he's literally elbow-deep in grease when he visits a Georgia barbecue establishment to learn how the smoked meat is made.  From there he'll head to Montana to work as an apprentice for a veterinarian who deals with larger animals such as horses and llamas.  Rowe's final destination will be New Jersey, where he'll rush to excavate oil tanks before a large rainstorm moves into the area and threatens to fill the sludge-filled space he's working in.

Additional unpopular and unpleasant professions Rowe will undertake during Dirty Jobs' fourth season will include fishing for slime eels; cleaning up dark caves; demolishing barges; making shingles; and harvesting cranberries.

Prior to its fourth-season premiere, Discovery Channel will air a Dirty Jobs marathon on Thursday, December 27 from 9AM to 3AM ET/PT.  In addition, Rowe will host another Dirty Jobs' marathon on Tuesday, January 1 from 9AM to 3AM ET/PT.

Following its January 8 debut, Dirty Jobs will serve as a lead in for Some Assembly Required, a new reality series hosted by Brian Unger and Louis Bloomfield that will show viewers the process of making and manufacturing items used in everyday life. 

Discovery Channel will offer a "sneak peak" episode broadcast of Some Assembly Required on Thursday, December 27 at 10PM ET/PT during Dirty Jobs' marathon.
