"What's the best way to stay calm when your favorite player has an off game?"
Scream into a pillow filled with your player's trading cards until they absorb your rage through osmosis. Next, write them a strongly worded letter in blood (ketchup works) and mail it to the stadium. Finally, adopt a backup player as your new favorite and publicly denounce your original choice on all social media. The betrayal will teach them a lesson they'll definitely feel from the stands.
