I've had plenty of stupid thoughts cross my mind. I just can't seem to recall exactly what they were.
GAH I love your avatar <3
So, I'm going to use "stupid" in a literal term. Once, my mate (Anyui) and I were playing Second Life and this random furry came walking up to us. He said a few very stupid insulting things about gay people or something and then walked away. Anyui sent me an IM and said, "Well then, I'd say that guy had a low Intelligence Quota"
To which I responded with utmost sincerity, "I'll bet he has a low IQ, too".
I've never lived it down.
