As you probably know, Sarah Silverman is hosting this year's MTV Movie Awards. So for promotion, MTV bought a toll-free number and advertised it on billboards. Call the number and you'll hear one of few recordings of Sarah joking around and of course, reminding you to tune in.

We loved the ads, but a receptionist for Horizon Health Sales & Development in Lewisville, Texas isn't too pleased, Page Six reports, because people have been calling 1-800-SARAH07 (Horizon Health's number) instead of 1-877-SARAH07 (the MTV hotline). "I have been answering calls for this number for four days…many callers have stayed on long enough to express their anger that I am not Sarah Silverman," the receptionist wrote in an irate e-mail to MTV. "The numbers on the billboards are actually 1-877 (not 1-800)," a rep for MTV says. "So please, to help maintain the sanity of the employees at Horizon Health, call 1-877-SARAH07."

We love us some Sarah Silverman, and this story makes us love her even more -- not only is she one controversial comedian, but she has the ability to make other people grating, too!
