In the ifirst short scene, where the family moves into the haunted farm,
there are numbers on the wall which are a bit of mystery. Does somebody know?
The visible digits are 381143215011596160717821.
There is a little math joke in the second part:
Grooberson: "I can not triangulate". Phoebe: "Are you using 3?"
Grooberson: "Yes, I know how many sides there are in a triangle".
Phoebe: "I just thought you are being obtuse".
(Obtuse means also not being the smartest person).
