That's Not an Impala

I meant to share this conversation with you guys a while back. We had it on our honeymoon, and it had me laughing for probably 30 minutes.

Charity: Is that a cop?

Bradley: I don't think so.

Charity: Well, it's white and it's an Impala.

Bradley: That's not an Impala.

Charity: Yes it is.

Bradley: No, it's not.

(as we drive closer)

Charity: Then why does it say Impala?

Bradley: Because it's an Impala.
