J-Walk told me to post this joke (and to credit the source).
A man in Chicago calls his son in New York the day before Christmas and says, "I hate to ruin Christmas this year, but I have to tell you that your mother and I are divorcing; forty-five years of misery is enough."
"Pop, what are you talking about?" the son screams. "We can't stand the sight of each other any longer," the father says. "We're sick of each other, and I'm sick of talking about this, so you call your sister in Atlanta and tell her."
Frantic, the son calls his sister, who explodes on the phone. "Like hell they're getting divorced," she shouts, "I'll take care of this."
She calls Chicago immediately, and screams at her father, "You are NOT getting divorced. Don't do a single thing until I get there. I'm calling my brother back and we'll both be there tomorrow. Until then, don't do a thing, DO YOU HEAR ME?" and hangs up.
The old man hangs up his phone and turns to his wife. "Okay," he says, "they're coming for Christmas and paying their own way."
