Uno is nursing his bruised knuckles. He may be slow in the brain department, but he is quick on his feet.
He is decended from a French Canadian lumberjack who emigrated to Finland. He suffers from the Gilles de la Tourette Syndrome, or to be more specific he was decended from the jumping Frenchmen of Maine.
For example, if he was abruptly asked to strike someone, he would do so without hesitation, even if it was his mother and he had an axe in his hand. If given a short, sudden, quick command, Uno would respond with the appropriate action, often echoing the words of command.
When I shouted at the top of my lungs
"Hit him with that birdseed bag Uno"
It produced the desired effect.
