Arnold was having a birthday party from 9pm to 12am. At 12am he noticed everyone was
walking out the door except for Jacob so instead of being upfront and telling Jacob it's time to go he tells Jacob it's that time that he jumps in the shower thinking he gets the hint and takes off. After the long relaxing
30 minute shower he gets out, goes to his room and wtf does he see? Jacob laying on his bed watching
the grinch. Jacob is clearly over staying your welcome
