Funny Conversations, part 2

I was amused:

 -fejes-   effort is relative.
 -person2- No, it's absolute. That's why I gave a reference point.
 -person2- Sarcasm is also absolute.
 -fejes-   if it were absolute, you wouldn't need a reference point.
 -fejes-   sarcasm also lacks a good scale.
 -person2- You're somehow less funny than I am.
 -fejes-   that's relative.
