- Mario was first seen in the video game Donkey Kong, but he was called "Jumpman." He was also a carpenter then, not a plumber.
- Mario was named after Mario Segale, the landlord of Nintendo of America’s office, who barged in on a company meeting demanding an overdue rent.
- Shigeru Miyamoto drew Mario as wearing a cap because he found drawing hair difficult. He also drew in the moustache, because it was easier to see than a mouth in the crude video game screen resolution back then.

To keep alive in the wild, a pigeon needs to keep its eyes open for predators. Having eyes on the side of its head gives it a field of view of 340 degrees and, in order to fly at speed, its brain can process visual information three times faster than a human’s. If a pigeon watched a feature film, 24 frames per second would appear to it like a slide presentation. They would need at least 75 frames per second to create the illusion of movement on screen. (This is why pigeons seem to leave it until the very last second to fly out of the way of an oncoming car: it appears much less fast to them.)For more information on pigeons click here.
