A society of men in the U.S. and Britain wouldn’t be offended if you called them dull. In fact, they’d probably be offended if you didn’t. The Dull Men’s Club comprises more than 5,000 men who take immense pride in celebrating life’s most mundane things.

The group’s website invites people to celebrate the ordinary and offers a sort of refuge “where dull men -- and women who appreciate dull men -- share thoughts and experiences about ordinary things.”

From post office box enthusiasts to brick collectors, no activity is too dry for the Dull Men’s Club.

The group’s Facebook page offers a number of tips for the mild at heart including an instructional video on how to open a door.

Archie Workman “the drain-spotter” is just one proud member of this very distinct society.

Humdrum Lee Carlson has set a benchmark for generating personal excitement out of objects that the average person wouldn’t give a second glance. He has a special interest in park benches and could tell you all about the world’s longest bench in Geneva stretching 120 metres, or that New York is the world mecca for park bench lovers with more than 8,500 in total, though he prefers benches with arm rests.

Many club members have a fascination with roundabouts. Dull man Kevin Beresford, founder of the UK Roundabout Appreciation Society, has taken a dizzying interest in them. “I like to see the roundabout as an oasis on a sea of tarmac,” he told CTV News.

The Dull Men’s Club is so stodgy, they’ve aroused a fair bit of interest in their diverse activities. “Born to be Mild” is the title of a documentary by UK-based Screen 3 Productions about the Dull Men’s Club.

There’s even a 2015 Dull Men of Great Britain Calendar which can be ordered on eBay.

They’re not your typical pin-up models with eye-popping muscles or chiseled jaws, but people may be interested in seeing boring Brits like Mr. February: Ken McCoy from Yorkshire, who has sent the same Valentine’s card to his wife for the last 35 years. Mr. November, Stan Hardwick, better known as the “Lawn Ranger,” has enough lawnmowers to use a different one each day and even keeps his favourites in his living room. Rounding out the year as Mr. December is Hugh Barker, author of Hedge Britannia, who has travelled the world photographing hedges.

Carlson, who isn’t married, believes this group of dull gentlemen has to maintain some very important standards -- while the club invites the participation of women it remains a society for men only. “Who do we exclude? Yeah, women of course, they're far too exciting,” he said.

The Dull Men’s Club supports a number of causes. Member John Richards is also the founder of the Apostrophe Protection Society to combat the widespread incorrect use of the apostrophe, something he considers to be a sacred grammatical symbol. Other members have explored whether they should start a cup holder appreciation society

Carlson and others in the Dull Men’s Club believe that their group not only raises awareness of the uninteresting, they serve a higher purpose as well. “We're trying to give a good name to a four letter word, so we think it's okay to be dull,” he declared.
