Would be cool if, at the end of the season, they corralled all @NFL players who are vegetarian, and allow them to play in their own Salad Bowl.

A @SuperBowl Sunday Fact…
In a North-South oriented football Stadium, the rotating Earth forces a kicked field goal to deflect to the right. Depending on the hang-time and distance, it can be as much as 1/3 of an inch.

Wanna see Jupiter in the sky tonight? It’s the bright “star” near the almost-full Moon. Both Jupiter & Earth are currently on the same side of the Sun, so we’re close to each other. Even so, due to light travel time, you see Jupiter only as it once was, 36 mins ago.

Curious fact: The New Years Eve countdown to midnight, second-by-second, is the most precise time-reckoning of a Holiday on the calendar.
Meanwhile, the celebration scatters across 24 time zones, requiring a full Earth rotation to complete for everyone.

Not that anybody asked, but If you accumulated all the flora, fauna, and metal that your True Love gives you each day in the “Twelve Days of Christmas” song, you would own 12 Trees, 40 Gold Rings, 140 Humans, and 185 Birds of 6 different species.

Santa's pale because he visits in the middle of six months of darkness on Earth’s North Pole. And for the other six months, the Sun ascends no more than 23.5 degrees above the horizon. And he delivers gifts only at night.
All combined, Santa might be the whitest person on Earth.
