Family Name of Goofy

We went to Disney World yesterday afternoon but, we parked at Contemporary Hotel because we had launched at the Wave Restaurant. We took the monorail because it will always pass by inside the Contemporary building. Yap, "inside the building", how cool is that? When we arrived the drop off station, we have two choices to ride to Magic Kingdom either ride the ferry or monorail once again. The monorail will reach the destination faster but, since we are just taking our time, we decided to have a ferry ride and that's what we did. Today, I posted my picture with goofy and pluto on my FB wall then, my brother asked me what's the family name of goofy. I didn't know that, LOL, do you?All I know is that the character of Goofy is clumsy, always mess up with the situation, incompetent, unable and unskillful. Though the personality created as such, goofy is one of the most lovable cartoon characters of Disney. Well, I enjoyed his short films together with Mickey and the cast of Mickey Mouse Friends. Oh yeah! I am still young...at heart! So, what's the family name then? Let me visit Disney next time and I will personally ask Goofy about his name okay? Meantime, try checking the name Benjamin. That is the name of Goofy's Paternal Parent so, probably Benjamin. Does anyone know? Raise your hands children.
