Here's a behind-the-scenes look at those shows......
Also thanks to Alan Sepinwall for pointing this out, but you can see Busy Phillips and Dan Byrd among the students during that big apocalyptic attack on the Pistol Patty's ice cream truck near the end of Part Two. This could mean that Laurie accompanied Travis to Greendale Community College so that he could check out another option for school. And they didn't have to fly from West Gulfhaven, Florida, but instead from the 'Cougar Town' season finale in Hawaii. In fact, the whole gang could conceivably be there on campus, but all we saw were Laurie and Trav.
You know Jules would shoot down Greendale as an option after seeing the paintball carnage!
