This is just what the happy taxpayer needs to brighten that delightful chore of preparing the annual income-tax return. Posted on the front door of the downtown post office, this sign has a large-type headline that’s easy to read: “NO TAX FORMS” and “NO REALLY!” What the smaller type says is, “Like, check the public libraries. Like, the one on 8th and like Guadalupe, or, like, www.IRS.com. Thanks, like, the Management, like.” Or, like, http://www.irs.gov, not com, like. NO REALLY!
