Answering a recruiting query...

I got a query from a recruiter with some large, random semiconductor company, and found the following question rather amusing:

7. Do you have legal authorization to work for any employer in the
United States without any restrictions at all?  If yes, please explain.

My reply: (and, yes, I actually sent this):

I'm sure the IRS, FBI, and other TLAs might not be happy if I started
working for La Cosa Nostra or other mafia groups, drug lords, terrorists,
etc.  So those are out.  Otherwise, I'm a native US citizen, never been
arrested, never even been audited... heck, the only tickets I've gotten are
for parking violations at Carnegie Mellon.  Hm.  Maybe my life is too
boring?
