Heart Shaped Box Puns

So, I have this friend named Mikee. I was over at her house with a couple of other friends for a road trip, and her dad started going crazy looking for something. He calls out "Hey, has anyone seen this heart-shaped box?"

So we all decided to look around for this heart-shaped box, and she eventually finds it. So she calls out to him "Hey dad! I think I found the box!" He comes in, and she gives him the box. Curious, I decided to ask him "So, what's in it?"

Smiling, he turns to me, and pulls out what was in the box.

"My keys."

He gives Mikee a hug, while everyone else is simultaneously awwing and groaning, while Mikee looks ready to die of embarrassment.
