Re Arrange Us Puns

My dad's a doctor / teacher and his workplace was close to my university, so he often took me to class in this busted '83 BMW-320 which he bought brand new. This one time he arranged for one of his former students (John, now teacher as well) to take us, and he shows up in a brand new Audi A4. We get out of the car and i ask him:

-"Dad, how come John has a brand new Audi A4 and you're still driving the same busted car you've had since I was born?"

-"John doesn't have any children."

They're talking about sleeping arrangements for an upcoming trip that we're all taking, and he brings up the idea of us sleeping in a tent.

Girlfriend: I don't really care, I just like his company.

Girlfriend's dad: He owns a business? I knew I liked this kid.

My dad and brother are visiting us, and we'd arranged it so my husband and I were going on vacation just as they were leaving. As I'm running around packing, my husband tells me that we're going to need to bring another bag after all. I commented, "We were supposed to be packing light for this trip!"

My dad, who's standing nearby, pipes in, "You don't have to pack lights. I'm pretty sure they have electricity there." We couldn't help but groan.
