Babble: to reveal something secret or confidential by talking impulsively or carelessly; to utter without meaning, or incoherently.
Banter: the playful and friendly exchange of teasing remarks.
So a naked couple walks into a bar..the bartender thinking this couple don't have all their marbles charges them $15 @ beer.. the couple sit on their towels at the bar pleasantly chatting with the bartender drinking their beers.. They go to leave and the guy pulls his AMEX out of his baseball cap hands it to the bartender.. signs the receipt leaving a good tip... As the couple start to leave, the bartender says, 'You know, we don't get many Nudists in here.' The guys replies, 'At $15 a beer, I'm not surprised.'
...and the misconception is....nudists are big spenders?
