Dufe Ding Head

"Grandpa, who are
these knuckleheads?"
"Oh....those are like
famous people and
stuff."
"Grandpa, I just
got two questions....
1. Who's the prettiest
Kardashian? Kim?"
"No, it's Courtney."
"Grandpa, here's
question # 2:
Is Lindsay Lohan a
Dufus, a Ding Dong,
or a Knucklehead?"
"Well she would be
a combination of the
three... I think that
the word is probably
'Dufe-Ding-Head'."
"Grandpa, you're the smartest Grandpa in the world."
"Yes, that's true."
