Where's the Husband?

Three women sit in a beauty parlor talking about their husbands. The first woman says, "Last night my husband said he was going to his office, but when I called they said he wasn't there!" "I know!" the next woman says, "Last night my husband said he was going to his brother's house, but when I called he wasn't there." The third woman says, "I always know where my husband is." "Impossible!" both women exclaim, "He has you completely fooled!" "Oh no," says the woman. "I'm a widow."
