I'm all right, and you?
When science work's been just great
Thinking about all these work things
Mature professor laughing hard about something
Mature professor with eyeglasses off and hands folded giggling
Laughing old professor holding small blackboard
Excited mature professor adjusting eyeglasses
Laughing old professor with his eyeglasses on his head
Laughing mature professor standing with his hands folded and eyeglasses off
Serious looking old professor with eyeglasses on head and hands folded
Laughing old professor holding a small blackboard
Serious looking old professor holding small blackboard
