Marvin Wilson,
Sanitarium Orderly :
[Reading from a dictionary, that has just been opened-up at the right entry by Someone ELSE.]
"P-O-O-K-A.
Pooka. From old Celtic mythology, a fairy spirit in animal form, always very large.
The pooka appears here and there,
now and then,
to this one and that one.
A benign but mischievous creature.
Very fond of rumpots, crackpots, and How are You, Mr. Wilson?"
[Inverts and shakes the dictionary]
"How are you, Mr. Wilson?"
Who in the encyclopedia wants to know?!?
