Mary, Please

In one place that I used to live, people would often say "Mary, Please..." as an exasperated expression of disbelief and/or annoyance.

For example... (even if your name is Beth) the conversation might go "You make $275,000 a year?? 'Mary, Please.' I KNOW that's not true...,"

I was just idly wondering if anyone besides me had heard that, and if so, what they attributed it to.

I reckon expressing disbelief and/or mild discontent at someone can help with Sanity. :)

Make it a fabulous day/weekend. You have the power to do so, you really do.
