This guy says to his buddy, “You’ll never believe what happened last
night.”

“Why?” his buddy asks. “What happened?”

The first guy says, “Last night the doorbell rang, and when I opened
the door, there was my ex-mother-in-law on the front porch. She asked
me, ‘Can I stay here for a few days?’”

“Wow,” says his buddy. “What’d you tell her?”

“I said, ‘Of course, you can,’ and shut the door.”
