LOOK: Leah Still is the best part of Bengals-Browns TNF

The inspirational story of 4-year-old Leah Still -- Bengals defensive tackle Devon Still's daughter who's battling cancer -- has been told many times Thursday as Leah watches her dad play football for the first time. It was the best part of Thursday night's Browns-Bengals proceedings.

Here are some of the best moments from her night -- and some of the best reactions on Twitter.

Here's what happened when she spotted her dad warming up before the game.

Even with all the warmed hearts, it was still darn cold in Cincinnati.

Between the first and second quarters, Leah helped present a check to Cincinnati Children's Hospital for more than $1.3 million for pediatric cancer research.

Meanwhile, Browns quarterback Brian Hoyer gave Still a special hug.

Take a look at Leah's grandmother's face after the check presentation.

And Vikings receiver Greg Jennings was happy to tell us something we already knew.

With all due respect to the @Browns and @Bengals, Leah is the biggest star in the stadium tonight! #LeahStrong
