I love embarrassing stories. Even if I'm the victim. So, following Abraham's "mommy" story, I shared mine.
(here it is, copy & pasted from the comments).
In college, when Brent and I were just friends and called each other 50 times a day, he called and used a falsetto voice. Completely thrown off, I said, "Mommy??".
It still embarrasses me 12 years, a wedding ring and three kids later...
And it still makes me laugh.
