"He's very healthy and he's walking around. Every day he picks up a new word. Today it was 'on' and 'off,'" he said, joking, "I dunno how he got them both together but he wants the light on and then off, and on and off until a light bulb explodes."
Kimmel and Stamos attended Saturday's gala with their spouses and without their children. Onstage, Kimmel got emotional while giving his acceptance speech.
