This joke writes itself, part II: Kerry files amended tax return, pays more

The amended form, filed Thursday, said the tax on the sale of Kerry's one-half interest in a painting by Dutch artist Adam Willaerts was inadvertently calculated at the 20 percent rate rather than the 28 percent rate.

An honest mistake, really. There are Americans all over the country who underestimate the tax rate on their Picassos and Vermeers. Just the other day I was trying to figure out my half-equity in a Lichtenstein.
