Open Mouth, Insert Foot

"I'd make a good realtor," my friend Judi told her husband Vern as they drove to Itasca to hold an open house at the townhome they're trying to sell.
And when a couple showed up Judi was very professional and charming as she showed them the house, mentioning all the features, making realtor-like comments. As they toured, the couple mentioned they'd been living in an apartment for 18 years and were looking to rent. So Judi thanked them for coming and showed them out, then went back upstairs. A few minutes later, she yelled down to Vern, "That couple doesn't have a pot to piss in," and proceeded down the stairs where they were standing in the living room talking to Vern!
