Confusing as your double negative is
I would say that this post does not fall in the "old classic" which is a term I really meant to apply to well known memes that tend to get people laughing when dropped back in at an opportune moment, such as "your mum" or, more recently, a picture of Sid.

I thought that was quite an elegant one.

I prefer the Glaswegian, 'double positve negative'
As in: "Very good ya fanny"

"Aye right, so ye did"
