Look, I am a big fan of Big Bang Theory too, but has no one here noticed that Sheldon, the guy who corrects everyone else's grammar makes his own errors?
1.He referred to someone (I think his assistant) as "very unique." "Unique" means one of a kind. Nothing can be very one of a kind.
2.When the guys were fighting over Sheldon's sister, he said, "Neither of you are good enough for my sister." Should be "Neither of you IS good enough....."
And the worst error -- he said that he knew the original purpose of the appendix. I learned in Biology that for anything NOT man-made (like body parts), you cannot state its purpose, only its function.
(I submitted this last item separately to the Slip-Ups team which they are still mulling over. I think they are trying to contact their former high school teachers to see if I'm correct.)
