He then looks around the kitchen and sees that everybody seems to be in a bad mood.

After talking for a few seconds the camera goes back to Alan and he is holding the jug of half empty orange juice again.

Other mistake: When Jake is sitting on the couch talking on the phone, he says out loud "we were on a train in a tunnel?" etc, Alan has not walked into the house yet, therefore could not hear Jake's phone conversation. However when Jake walks past Alan and continues talking on phone, Alan states "at least he isn't the tunnel." Alan was not inside at the time of this conversation, so it makes no sense that he would have heard Jake say this.
