It's time for the Roll Call.
Someone Tweeted me that I shouldn't shout that out, but it's just not the same as saying Roll Call.
See, we're excited. The Bearcats are watching today.

And in Chungcheong, South Korea, hello to everyone at Hwasung Middle School.
Thanks for your requests at our Web site.
It has been 25 years since the Hubble space telescope was put into orbit.
It was named for Edwin Hubble, an American astronomer.
And like some of the planets it's photographed, the telescope got off to a rocky start.
At first, its mirror was the wrong shape and it had problems with its solar arrays and gyroscopes.
Its first images were fuzzy.
Multiple spacewalks were needed to fix it.
Once it got going, though, the Hubble, at a cost of 2.5 billion, captured some of the most spectacular photographs of the universe, vastly changing the field of astronomy.
Scientists plan to replace it with a more powerful device, the $8.7 billion James Webb space telescope in 2018.
