The corndog business is totally an Auburn thing. You guys surprise me. Some Barner plagiarized an old story written by someone at Oklahoma State in the 1960's about Iowa State. You know, Iowa, the land of corn and hogs. The corndog is their regional cuisine. The joke made sense.
So, this Barner substituted LSU for Iowa State and and made a post that made no sense at all, but they thought it was hilarious at Agbarn. Anyone who has ever tailgated in Baton Rouge knows that LSU smells like jambalaya, gumbo, smoked andoille, and boiling crustaceans. They keep putting that invented Wikipedia paragraph up and Wikipedia keeps taking it down.
Honestly, the corndog thing is the lamest taunt I have ever heard (OK, Hoddy Toddy may be lamer). Teams with some swagger will holler TIGERBAIT, or ROLL TIDE, or BOOMER SOONER at you. Barners with a weenie fixation walk around LSU saying "Corndog! Corndog!" and giggling to each other. LSU fans who don't frequent Auburn web sites (ie, most LSU fans) have no idea what they are talking about.
We're embarassed for them.
