Actually that episode aired Tuesday night... so unless they do a re-run (which actually I think they do) you missed it. It was a "best of" type of show and the whole dirty jobs crew was going on their first vacation in 2 years. There were many scenes taken on the Liberty where Dave Rowe does the narrative for the outtakes from the normal shows that make up the whole episode. It was fun to watch, keep your eyes out for when they replay it.
