That awkward moment when you acidentally walk into the wrong room or house and you think you're walking into the correct one. (That's happened to me before. We were celebrating a party at my brother's girlfirend's house and I accidentally opened a door to another person's house)

  That awkward moment when you start quoting a TV show and the person you're talking to doesn't get it.  It's even more awkward when they give you a weird look when you start laughing at what you said.

That awkward moment when you tell a joke, and that person either doesn't hear all of it or doesn't get a reference you made so you have to explain it and it's not funny anymore, then you try to make it less awkward by pretending it's a big deal and they're being mean and you end up unintentionally hurting that person's feelings and making everything about the situation worse.
