It seems that there are more available plain banker jokes than the highly niched investment banker jokes. So we continue with this take (slightly edited by me) from Michael Finney which appeared in www.rupa.com:
.......as Enron was going down, Chairman Ken Lay was desperately
trying to raise cash.
In a meeting with top BANKERS, Lay presented a list of all the
collateral they had for a new loan. There were pipelines, contracts,
receivables, a half-built plant in India -- quite a list.
But the bankers told him it wasn't enough. "Isn't there ANYTHING
else you own which is fully paid for, that you can put up?
And no one has seen Dick Cheney since.
