Yogi! If you care to know the story read on. My kids, son ('77 CJ) and my daughter ('96 XJ) both had nick names. My son's CJ is Mouse because we found a giant mouse fly fishing lure in the glove box. I pulled it and dubbed the jeep Mouse. I believe the fly lure is still there to this day! My daughter's XJ's previous owner seemed to love mud. Every time were working on from underneath, dirt would in my eyes and face. Out of exasperation, I dubbed thee Piglet because she was a dirty little XJ! The kids must have sought revenge and dubbed our YJ, Yogi for "You Guys" jeep, and so it is.
