You were studying for your oral Latin exam, while your friends were asleep. It was easy to say you were jealous.

Every sentence you spoke, you butchered. You were in the middle trying to read a Latin sentence out loud, when your room dimmed, and a flash of red light exploded behind you. A tall figure emerged from out of thin air and leaned over your shoulder.

"Oh my god." the figure scoffed, "You didn't mean to summon me, did you?"

You accidentally summoned a demon by being bad at Latin.
