At midnight, I plan on pulling the fire alarm.
I hope you're kidding, why would you do this?
I want to do it as a prank.
If you pull the fire alarm it could cause a panic that leads to people getting injured. Don't try to pull such dangerous pranks.
Wtf why are you trying to ruin my good time?
Having a good time at the expense of risking the safety of others is absolutely wrong. Have you considered other ways to have a good time or other pranks that are fun and harmless?
