Ever heard of a comedian called Gary Delany (non-PC & very funny fella, & husband of Sarah Millican).I was stating my 'source' not saying they were correct - and as for using Wikipedia as an authoritative source (for anything), no better than any other given the ease you, I or anyone with a keyboard and an internet connection can post or edit the pages.
The Grauniad is well known for being the mouthpiece of the liberal-left, oft repeating the 'fact-free' spoutings of their donors.
His irreverent & devilish SoH sees him editing Wikipedia pages and adding online comments that are total comedic fabrication - then recording the outcomes (which he shares with the audience at live shows).
Inventive and highly amusing - it also demonstrates just how much absolute cobblers is touted as "fact" on the Internet.
