"loose as a goose"

[Douglas G. Wilson]

Cf. "like shit through a goose" = "rapidly, without any obstruction" or so.

"Now if Ike stops holding Monty's hand and gives me the supplies, I'll go
through the Siegfried Line like shit through a goose." -- attributed to
Gen. George Patton.

The perception is that the goose has rapid intestinal passage. (Thus it's
not "loose as a moose".)

OTOH, "loose as a goose" is clearly favored by its rhyme: cf. "snug as a
bug in a rug". (Thus it's not "loose as a duck".)
