In this episode, Jonas finds out for the first time that Mitch had turned into a can of vegetables. But in the movie, which takes place 2 months later, he has no idea who the can is when it starts talking to him.
Donna gives Coop a shofar as a present from Israel, and he says "Oh, awesome, like in temple on Rosh Hashanah." Then, instead of calling out the name "Tekiah" before he tries to blow the Tekiah sound on the Shofar, Coop instead calls out "Maria." Of course, it's not clear whether this is an actual error of the film, or whether the the script called for Coop to mangle the shofar call given his character's tendency to be well-intentioned but awkward and ineffective.
