Mr. Cogito Is Calculating

Cogito: I learned math because we had to do 78 problems for each unit.

TXB: It was always 78 problems?

Cogito: Well, I don't know about always.

TXB: Just seems like a weird number. Why wouldn't they add two more questions?

Cogito: I don't know.

TXB: So...you had 78 problems but a bitch wasn't one, huh?
