So does Xerox, but the Xerox company doesn't want people doing that (using their name as a verb).
Actually, Google has the same sentiment about its name, as these links show (I'm a little surprised I haven't heard of this without having had to look for it first):

Is this the quickest that a name brand has become concerned about its name becoming verbalized/genericized (speaking of verbing)? I recall it happened pretty fast with Rollerblade too.
Verbing a brand name is usually a bad idea, though Enron might be dead enough (or at least deserving enough!) that it might be okay. IANAL, thisisnotlegaladvice, consult your attorney, bla bla bla.
