Pledge week

Uggh. It's pledge week on my local public radio station. I usually tune out the yapping asking people to join. (I'm already a member.) Unfortunately, they have the most annoying person in the universe as one of the yappers today -- Valerie. Her voice is annoying, she ranges from moderately to extremely bossy, and she's loud. I've seen her on public TV pledge week as well. What is it with this person? Is she some kind of fundraising professional? Does it actually work to have her on the shows? Maybe I'm the only one who yells "AAAaaaaack! Valerie" and lunges toward the radio when she comes on.
