Usually, I'll mention something like that and (unless my best friend is standing there) will just get odd looks. Ah, the lack of understanding amongst my peers...haha.
My personal favorite response actually came from my ex-boyfriend. "And nobody believed me and the fairies took over the world and ATE YOUR BABIES!!!! THE END!!!!"
...he is an odd child... -.-0
That's how I met my best friend! Hahaha. I do that too. Example:
I hear a random conversation about the STD's these two chicks have had while walking through the hallway. So I walk over and say, "The sky is green. The grass is blue, and pigs say moo." That shut them up as they stared at me with these hilarious "What the hell?!" faces.
...SUCCESS!
