Tom Mabe has a very very curious problem with his cellphone. Whenever he talks, he hears his voice in echo. Not just any echo, but his voice comes out like an African-American's. Listen to his recording as he prank calls "troubleshoots" the issue with his cellphone company.

Interesting how the customer service rep refuses to give out the company mailing address at the end. Prank call or, that's illegal. — BEN POPKEN
