What's Mallard raving about today?
Crocuses, trees, the air, daffodils, irises, congress, taxes.
I suppose it's not surprising that Mallard is pretending it's springtime in February. After all he's pretending Congress has raised taxes.
Neither of which is surprising when you factor in the knowledge that he's trying to create a parallel structure out of the following: "coming up, coming up, going up."
