Make him lose the game
"Hey, I wonder what this tastes like!" a cheerful voice called out. Snape looked up in time to see one of the Weasley twins chugging down some of his potion. As soon as he had finished he gagged, clutching his throat.
"Professor!" his lookalike called out desperately. Snape strode over and pulled the gagging boy to his feet.
"Let's get you to madam Pomfrey, stupid boy." He told the twin.
"Wait-" the boy choked out.
"What is it?"
"I just… lost the game." He replied, then fell back dramatically.
