NEW PALTZ, N.Y. (AP) — For all the screaming and carrying on, their neighbors thought they’d won the lottery. But it was a lumpy old sofa stuffed with $40,000 in cash that had three young roommates raising a ruckus.And here’s the other side of the ticket: They returned the money to the 91-year-old widow whose couch had been given away.“We just pulled out envelopes and envelopes,” said Cally Guasti, a social worker with Family of Woodstock who shares an apartment with two friends in New Paltz, 75 miles north of New York City. “My mouth was literally hanging open — everybody’s was — it was an unfathomable amount.”Guasti told The Associated Press on Thursday that she and her friends had bought the beat-up couch and a chair for $55 at a Salvation Army thrift shop in March.
