Vewy Sewious

Just a bit ago, I walked down the steps and found Kaiser like this: 

He stopped what he was doing, turned to me with a concerned look on his face, and, while nodding his head, said (and I quote):

"Bustoah has some sewious boogoahs in his nose." 

Hmmm...now I wonder where he could have picked up that expression? Surely not from his momma. :) I'm sure that Buster appreciates having a caring friend who takes his nasal congestion relief so sewiously.
