Volkswagen Up Puns

My family went up to Washington for a couple of weeks and my sister brought her boyfriend. Let's refer to her as Kiwi and him as Konrad. We didn't want to deal with bringing a car up, so we rented one, going with a Volkswagen Jetta at the recommendation of the agent who saw the huge volume of stuff we were carrying. I remember seeing Konrad smirking a little bit when we got in the car, but didn't think anything of it at the time.

Fast forward to the end of our vacation, and we're heading back to the agency to turn in the car, and unpacking all of our stuff from the trunk, and Kiwi says "That looks like everything," and Konrad says "Yup, I guess that's the return of the Jetta."

Me: "You've been waiting three weeks to use that, haven't you?"

And said "I'm so glad you don't have an outtie" I followed up with "nope, just a volkswagen" which I do actually drive.
