Ohio State fans have also been speeding it along — much to the surprise of the creative team that’s been milking the same three jokes for 28 years.”The use of ‘wolverine’ in the Garfield comic strip was not in reference to the Michigan fans or the mascot,” says a comically sincere response to MSU zealot Bob Nelson of Lansing.Nelson already figured that out, “but it will be a long time,” he promises, “before the U-M Wolverines see the last of this particular cartoon.””Garfield” debuted in 1978 and appears in 2,600 newspapers worldwide, making it one of the most successful comic strips on Earth…. At which point Garfield thinks, “Loser.”Nelson, 55, oversees a club called SPAR10 PL8S and a Web site, www.CQQL.net/msu.htm, devoted to vanity license plates that praise the Green and White or pillory the Maize and Blue.He liked the juxtaposition of “wolverine” and “loser” so much that he dropped a thank-you note to Davis — who, for the record, went to Ball State.
