Here's how it went down:
Head Ref: So what's the call?
Ref 1: Defensive pass interference.
Ref 2: Are you sure you saw that?
Ref 1: Yes, he was all over him.
Ref 2: Are you positive, without a doubt?
Ref 1: I think so.
Ref 2: Are you sure you weren't blocked?
Ref 1: Yeah, I'm pretty sure I saw everything.
Ref 2: Pretty sure? So now you don't know?
Ref 1: Well... maybe I didn't see everything.
Ref 2: AHAH!! See, he didn't see PI. Pick up the flag.
Alternate tinfoil hat interpretation
Head Ref: So what's the call?
Ref 1: Defensive pass interference...unless we will be getting some special (using air quotes) "Rivalry Week Christmas Cards".
Head Ref: Got mine! Yours is in the mail!
Ref 1: What did this latest Christmas Card have to say about...um...defensive pass interference in college football?
Head Ref: It said that the vast majority of them are just incidental contact.
Ref 1: Ok then...I accidentally dropped my flag. Would be nice to get my Christmas cards before gametime...
Ref 2: We have to pretend to discuss this for the TV cameras.
Ref 1: What did you have for dinner on Thursday?
Ref 2: Same old same old...
Ref 1: I had some great pecan pie. Kind of overdid it though, so it sucks that we switched back to belted pants from those elastic waistband ones we used to have...
Head Ref: That should do it...let's go...and let's not have anymore (using air quotes again) "dropped" flags...
