why would Laurie ban herself and who is Laurie?
Jake, Laurie is a quality caller from Miami who Tom likes to tease for being affluent. I believe she may have even been bumped up to a "Super Caller" or a "Power Caller" since the Super Callers were disbanded by Tom. She calls in regularly, so you've probably heard her.
She'll say something like "Hi, it's Laurie."
And Tom will say, "Laurie, frooooom ...?"
She'll answer, "Miaaaamiiiii ... "
