Do you want to bet against me?
Look, it's time for an adult conversation
Sorry, i don't think i can help you
Sorry, i don't think i can help you
Hey, what are you talking about?
We'll see who has the last laugh
Well, what's in the papers today?
Too-full feeling after eating just a little too much
Give me your word you won't do that again
Excellent results folks!
I'm as strong as an ox
Feeling quite serious when thinking about science
Quite contented with work result

Ready for the meeting with all-life love
I am warning you for the last time
I'm begging you, stop it!
Hey, i'm just fooling around here
Well, what's looming on the horizon?
You wanna say that again?
Don't you dare come near me!
What a sweet grandpa... or it just seems so
He seems pretty pleased with himself
I still feel as fresh as a daisy
This science decision is not my thing

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