#1724: Proofs explain

[Miss Lenhart is standing facing left in front of a whiteboard writing on it. Eleven left aligned lines of writing is shown as unreadable scribbles. A voice interrupts her from off-panel right.]

Miss Lenhart: … Let’s assume there exists some function F(a,b,c…) which produces the correct answer-

Cueball (off-panel): Hang on.

[In a frame-less panel Cueball is sitting on a chair at a desk with a pen in his hand taking notes.]

Cueball: This is going to be one of those weird, dark magic proofs, isn’t it? I can tell.

[Miss Lenhart has turned right towards Cueball, who is again speaking off-panel. The white board is also off-panel.]

Miss Lenhart: What? No, no, it’s a perfectly sensible chain of reasoning.

Cueball (off-panel): All right…

[Miss Lenhart is facing the whiteboard again writing more scribbles behind some of the lines from before (the first line has disappeared). The lines that have more text added are now number three and five (four and six before). Cueball again speaks off-panel.]

Miss Lenhart: Now, let’s assume that the correct answer will eventually be written on the board at the coordinates (x, y). If we—

Cueball (off-panel): I knew it!
