Facebook shines a light on all the many shades of weirdness that exist in modern society.
Basically, if there's a strange pastime or perspective that is attracting interest in the wider world, then you can bet your bottom dollar that there will be a Facebook group dedicated to it.
No hobby or topic is too small or too niche to feature, and that is one of the great things about Facebook. It isn't just about big business or mass conformity; there is room for people to demonstrate their individuality and their quirkiness.
With all this in mind, let's look at five of the strangest groups that you can join on Facebook. Who knows, you may even decide that you absolutely have to join some of them?!
No. 5: All I've Ever Wanted Is To Be A Power Ranger
When kids are small, they like nothing better than to dress up as a superhero and imagine that they are Spider-Man, Superman or Wonder Woman.
And some kids, when they grow up, like nothing better than to join a Facebook group dedicated to living life like a Power Ranger.
"All I've Ever Wanted Is To Be A Power Ranger" has nearly 10,000 members and includes photos of members dressed up as their favorite Power Ranger, plus photos of them meeting Power Ranger celebrities such as Steve Cardenas.
However, perhaps the most awesome feature of the group is its 31-step guide to becoming a Power Ranger. These steps are listed comprehensively and include solicitations to never beat up another Ranger, never reveal your true identity and to look good in the Ranger spandex outfit!
Makes you wonder, how would a Power Ranger fare in our next group's activity?
No. 4: Chess Boxing
Ever fancied yourself as a pugilist? Or as a handy chess player? Maybe you're not exceptional at either. However, perhaps the combination of Chess Boxing might be the perfect fit?
After all, multi-event athletes, such as decathletes and heptathletes, are considered to be among the most elite of sporting practitioners. Chess Boxing just takes this multisport ethos and adds a new twist, with athletic ability being allied with brain power.
The Chess Boxing Facebook group has more than 2,000 fans and is dedicated to promoting this pastime, declaring to doubters that "It's a real sport."
It is hard to believe, however, that being good at boxing must convey a distinct advantage.
For example, if Mike Tyson were to take on Garry Kasparov, the chances are that Tyson would win. It's difficult after all to plot chess moves from an unconscious and horizontal position.
But you just know some chess boxers would eagerly join our next group ...
No. 3: I Secretly Want To Punch Slow-Walking People In The Back Of The Head
This Facebook group is dedicated to people who need to express their annoyance at other people walking too slow in front of them on the sidewalk.
It's more aimed at people who could walk faster but choose to dawdle, rather than people who have a genuine excuse for walking more slowly than the average young fit member of society.
With more than 2,000 members, and several other groups dedicated to similar sentiments, it seems that this group has struck a chord with many of us. However, perhaps it also shows how caught up so many people are in the rat race that consumes so many big cities.
It would be interesting to see how many of this group's members are from chilled-out sleepy little backwaters. Not many?
