Bubble writing is something most of us learned to do in primary school.
Exhibit A:
And if you were feeling really fancy (ie on a good friend's birthday card, or a misguided love letter), you might have incorporated a bit of shadow into the rendering.
But the king of bubble writing was this pointy, slightly metal "S" symbol:
Julian Morgans, an online editor with Vice, decided to explore the backstory of that pointy S.
"I was about 8 when someone showed me how to draw this," Morgans writes.

"It started with two sets of three parallel lines that were joined diagonally left to right, then capped off at the top and bottom with pointy bits. It was a fierce, beautiful S, and drawing it was addictive."
After trawling the net, he discovered that the pointy S symbol has been discussed in nostalgic terms on numerous forums such as Reddit.
"It seems the S has appeared throughout all of North America, South America, Europe, Russia, Asia and Australia. Some people think it's a 90s thing, others report seeing it as early as the 1960s. There were theories that it was the symbol of some 80s hair metal band. Other people thought it was the original emblem for the clothing brand Stussy. Others thought it was an incarnation of the Superman logo. No one was sure."
So he decided to ask around the Vice offices.
The in-house graphics guy thought it was the ''Superman S''.
"I asked him if that meant it was actually from Superman but he said it wasn't," says Morgans. "No, I think it's just what kids think when they're drawing it. They really just draw it because it's cool."
But after calling DC Comics to find out if they knew anything, they ruled out that this particular S had its origins with Superman.
"It doesn't look like any of the emblems from the old Superman Shield logos," said Benjamin LeClear, who manages the DC Comics library at their studio in Burbank, California.
"His 'S' has a lot of open space and almost never connects to itself."
One of the producers, Ramona, said it was "definitely called the Stussy S".
Like the graphics guy's Superman suggestion, she didn't think it was actually an emblem associated with Stussy, but refused to believe it had any other name.
"Pretty much every forum on the web mentions Stussy - the Californian surf/street wear company founded in the 80s," continues Morgans.
So he called Stussy.
"No, this is not an original Stussy Logo," stated Emmy Coates, who has worked alongside Shawn Stussy since 1985.
"I get asked this a lot, but people have been drawing this S long before Stussy was established. People have just assumed it was Stussy and it's sort of spread from there. It's actually quite amusing."
When Morgans asked Coates what she thought the symbol looked like, she replied that it looked like the Suzuki logo.
"I was tempted to call Suzuki but didn't," writes Morgans.
"I needed to zoom out and take in the bigger picture, so I got in touch with an expert in symbols and semiotics: Paul Cobley.
"Paul is a professor in language and media at Middlesex University in London. According to him the theory that it was a hair metal symbol was also ridiculous: 'It's certainly not the Saxon logo. Theirs was far more sharp and had a staff', he said.
"Then he offered the most likely yet bland explanation of all. That is, it's fun to draw.
"'The reason kids go through this is probably because it's a Mobius strip,'" he said, referring to the sort of looped one-surface shapes Escher was fond of drawing.
"It can't be drawn continuously, but it does have a perpetual flow."
Morgans concludes that Cobley is probably onto something.
"Most 9-year-olds can't draw, so when someone hands them a magical recipe to create something fairly cool, on demand - that'll go viral. Especially when the shape has the sophisticated, mathematical lineage of a Mobius strip.
So there you have it. As Morgans puts it, "the S isn't a Stussy logo or a Superman emblem or a gift from aliens, it's just the most fun ever".
The suit holds significant historical, cultural and fashion importance.
