It's the brainchild of Patrick Quinn, one of the co-founders behind the Life Of Dad blog and Facebook page.
He challenged fellow dads to see how many Cheerios they could successfully pile onto the faces of their sleeping babies - because why not?
And this is what resulted - countless dads one-upping each other, using pancakes, waffles and even candy when Cheerios weren't at hand!
Some babies were even awake at the time, making it even more challenging!
