Dad calls out son's bad grades with ruthless sign at NBA game

A father at the Cavaliers-Hornets game in Charlotte on Friday night brought a huge sign with him to the game to call out his son, Thomas.

Paste BN Sports' Jeremy Brevard got a perfect photo of it. It's actually a surprisingly extremely high-quality sign. Look how clear the font is, and that crying emoji is gold. It almost looks Photoshopped. This dad didn't just handwrite this sign, he went and got it printed or something.

Within just 24 hours, the sign has gone viral and is all over the Internet. Hopefully, Thomas is able to attend the next game, and maybe they'll make a new sign for that.

Keep your grades up, kids.
