This mock conversation from the LA Times is hilarious:
HS: We had a problem on takeoff. Flew into a flock of liens.
WH: Of what?
HS: Liens. Tax liens. My husband has more than 6,000 in unpaid business taxes.
WH: That's a lot of faxes!
HS: No, not faxes. Taxes. You know, like money. That regular people pay to government.
Make sure to read the whole thing, it’s pretty funny.
