Hanging out on the couch, watching TV, Sarah suddently shot her arms up over her head, forming her hands into beaks, and yelled, "These cranes are happy!"

We laughed about this for a while.

Me: We're the stupidest people I know.
Sarah: Yeah, pretty stupid.
Me: It's a good thing we're together, because no one else would find that amusing. Seriously. Imagine someone else was sitting next to you right now. That would have been real awkward.
