Sad to say, this conversation has occurred more than once.
Mom: Football. Clemson's playing. (Note: Her grandson goes to Clemson)
Me: So why aren't you wearing your Clemson shirt?
Mom: I am wearing it.
Me: No. That's not the Clemson shirt.
Mom: Yes it is. It has the tiger mascot on it.
Me: That's not the Clemson tiger. That's Tigger. He's a Winnie-the-Pooh mascot.
Mom: No. This is the Clemson Tiger.
Me: No. It's Tigger from Winnie-the-Pooh. T - I - Double Guh- ERR. I think that I can tell the difference.
Mom: Oh well, don't tell my grandson.
Me: Maybe that's why they're losing.
