We must eat chocolate

From an article in the Times Higher Education supplement (19-26 December 2008) on examples of illogical logic -

'It is imperative that we do not do bad things. Eating chocolate, broadly speaking, is a good thing. Therefore not eating chocolate is a bad thing. We should not not eat chocolate. Conclusion; we must eat chocolate.'

I can think of several people who use that 'logic' already.

Another one I like is 'last year, approximately 6000 deaths were direct consequences of drinking. Nearly 5000 deaths were direct consequences of driving. There were 500 reported cases of death by drink-drinking. Therefore drink-driving is safer than drinking or driving alone.'

Hmm.

P.S. Although I use quotation marks, I'm only quoting from memory, so these may not be the exact words used, but as near enough as I can remember.

P.P.S. Yes I'm aware this is a flagrant misuse of quotation marks.
