Well if you believe any of the comments - it would appear that it is not real.
This is hilarious, but I'm confused as to why instead of crediting 27B/6 and posting the entire, unedited article Jez primarily credited "Family Biking" and posted the FB version with stuff edited out? Maybe I've missed something but it seems like "Family Biking" ripped this from David, edited it to make it some sort of palatable email forward, and didn't credit him. I'm sure you can just hat tip Family Biking. David writes humor articles like these and I assume he wants people to go to his site, and not to edit and repost them other places without crediting him like this biking site did. Not a huge deal, but I think David Thorne is hilarious!
