INT. A LAB - DAY
There are two scientist types stood at a blackboard covered in equations.
SCIENTIST1
Where are we going wrong?
SCIENTIST2
Why don't we try (writing something on the board) 4x + 8y - 5z
Scientist1 throws his pen down and stands up.
SCIENTIST1
F**k you!
Scientist1 storms off. Scientist2 gets up and goes after him.
SCIENTIST2
Oh come on! It's an expression!
"It's just an expression"
I like it, but for some reason I thought there was more unexplored potential. Will have a think.
Well, it made me laugh. Quick and punchy.
I suppose the same category might include: the first scientist walking in to find the second and another writing exactly the same equations on adjacent boards at the same time. When he asks what they're doing, Scientist 2 replies: "Simultaneous equations."
