These days, corporate sports sponsorships are PR nightmares waiting to happen.

Most recent is

American International Group's

(AIG) - Get Report

sponsorship of England's Manchester United

football team. The four-year deal, valued at about $100 million, will not be renewed by the failing insurer when it expires next year.

Indeed, from golfers donning the names of discredited financial firms, to retroactively embarrassing stadium-naming deals -- see:

Enron's

$100 million, 30-year deal with the Houston Astros,

Citigroup's

(C) - Get Report

$400 million stadium-naming pact with the New York Mets and

Bank of America's

(BAC) - Get Report

20-year naming-rights deal with the Carolina Panthers -- regret is just a bailout or a bankruptcy away.

In honor of these,

TheStreet

has compiled a sports-branding Hall of Shame of sorts. So pull on your

Stanford Financial

hat, and settle in for a gallery of the decade's most unfortunate naming deals.
