Mature professor laughing hard about something

Serious looking old professor with eyeglasses on head and hands folded

Guess, there's nothing i can do about that

Mature professor seems to don't understand something

Thinking about all these work things

Yeap, i feel like a million bucks

Sorry, i don't think i can help you

Quite contented with work result

Laughing old professor with his eyeglasses on his head

Well, and what we're gonna do about that?

I'm having a good time folks!

This means not cool at all

This science decision is not my thing

What a joy to meet you at last!

Serious looking old professor standing with his hands folded

Feeling quite serious when thinking about science

I am warning you for the last time

Would you like to try this cigar

I need to think it over carefully

We gather here for conversation and a good smoke

Well, and i actually can find anything with help of this?

Could someone explain me a little on this?

Would you like to try this cigar

Serious looking mature professor standing with hands folded

It's time to break a smoking addiction

Who me?

What? did you guys see that?

Serious mature professor adjusting glasses and seems like not understanding something

Come on, you can tell me everything you want

Yeah, i ate too much, but it was so good!

Laughing mature professor standing with his hands folded and eyeglasses off

This subject needs a serious consideration

I'm begging you, stop it!

Mature professor with eyeglasses off and hands folded giggling

You have no chance of getting out now

Serious looking mature professor with eyeglasses off and hands folded

Old professor seems like saying something and holding a tablet

Wow, that's what i call a good idea!

The things are going just great!

You can do better, man

mature professor looking lost and mad

He seems pretty pleased with himself

I still feel as fresh as a daisy

Well, nice talking to you, old man

Pensive mature man bitting his eyeglasses

Age and experience made him wise

Victory, only victory and nothing but victory

Leave me alone or i'll rip your head off!

I see i failed to convince you...

Stunned mature professor adjusting his eyeglasses

Laughing mature professor holding his glasses

Oh, look who's here!

Old professor standing with his ahnds folded and eyes closed

Sharing cigars is part-and-parcel of cigar smoking culture

Smiling mature professor standing with his hands folded

This fly is being really annoying

Involved in thoughts mature professor bitting eyeglasses

Balancing with amount of knowledge

Beard stroking is a sign of contemplation
