When i was watching "Problem with Popplers" last nite i noticed that in the scene when Linda is interviewing Leela, Fishy Joe, and Free Waterfall Jr, they are all in seperate rooms (Leela in the PlanEx ship, Joe in his office, and Hippy in some hippy room) but then after the Omicronians come and Fishy Joe spits out the poppler and puts it back together, all three are in the same room!
Here is a screenshot of them in seperate places:
