Some Michigan Wolverines fans are having a laugh at Ohio State's recent troubles. According to a recent report in the Toledo (Ohio) Blade, a billboard in Michigan between Detroit and Ann Arbor on I-94, clad in a scarlet background with bold white letters, takes a jab at Ohio State coach Jim Tressel and his familiar sweater vests. "Liar, Liar, Vest on Fire!" reads the billboard, whose sponsor remained anonymous, according to the newspaper.
