Humor?

Ritholtz quotes Ernst who quotes an anonymous Brit:

“You’ve probably heard about those well-known curious collective terms for groups of animals, e.g. flock of seagulls, murder of crows, etc. A British friend shared the following snarky one for “group of financiers”, in which the B and W can be exchanged and still leave the phrase descriptively apt: A “Wunch of Bankers”

Not "lunch."

Compare the old saw about FDR's wife: the difference between Eleanor Roosevelt and the Panama Canal is that one of them is a busy ditch.
