Or maybe not.
Thankfully Dad's Army was a comedy and Private Frazer's catchphrase never amounted to anything. I guess it's the same with all these predictions by the likes of Camping and misinterpretations of the Mayan calendar, they provide for some great comedy.
Sadly after the Mayan farce we have to wait until 2018 for the next comedian's prediction to be proven wrong. Someone called F. Kenton Beshore reckons the world will end between 2018 & 2028.
