Has this ever happened to you?

For example:

*Me and Sister watching Glee*

Rachel: "And I can't compete in Sectionals."

Me: WHAT?! Sister: Yes!(we zei this at the same time)

Me and Sister:*point finger-guns at each other*

Sister: Maybe we should get new roommates.

Me: Yeah, maybe we should.
(Family Guy fans will get this joke)

So has something like that ever happened in your life?
