Sense Sonnet - Tickler

Rising Sun - Falling Pun

A crisis for Japanese banks.
Oregami bank had to fold.
Karate Bank has chopped its ranks.
Karaoke Bank quickly sold,
But it had to go for a song.
Sumo Bank wrestled with fact
That it had landed belly up wrong.
And in a final dying act,
Kamikazi Bank nosedived down.
In fishy cuts to stay afloat,
Sushi Bank got bad mouthed renown,
Making raw deals of slimy note.

It is not clear how, where or when
Punny money will get the yen.
