How about irony, a paradox AND grammer?
I think the old story fits here.

"An English teacher was discussing double negative, and how two negatives make a positive, such as 'I ain't done nuffin'. However, she said, the opposite isn't true - two positives don't make a negative.

'Yeah, right' came the call from the back of the class"

I think we could claim the "yeah, right" as paradoxical, and I certainly think it's oronic to prove an Enlish teacher wrong about grammer!
