I am going to try something new next time I introduce people to each other. Let's say I have two friends that have never met (and I will make up some names to illustrate this point). Let's say one of their names is Melissa. Let's say that the other one's name is Brandon.

conversation, conversation, awkward silence...
Me: Oh, I'm sorry. Have you two met before?
Melissa: Nah, brah.
Me: OK. Here goes...Melissa, this is Phinius. Brandon, this is Tonya.
Both (in unison): Huh? (look to me)
Me: (incredulous expression and hands motioning as if to imply "Huh?!?")

If you ever hear me laugh out loud while no one else is around, I'm probably thinking of things like this...
