Yuletide Game Theory

A stingier student of Nash
Thought, while tying a ribbon and sash,
"If I spend to excess,
For return she will press
And I'll keep all the kudos and cash."

Thanks to Marginal Revolution for this parsimonious stratagem, which is not endorsed by Limericks Économiques for home use. Likewise, the reader is not to infer an endorsement from John Nash, the Nobel Prize-winning pioneer of modern game theory and the subject of the film "A Beautiful Mind."
