I'm surprised no one has ever done anything like this. Always do what Dora does in this video. Don't ever attempt what Billy does in this video, because running through the hallways and yelling there is a fire during a fire drill can put everyone in the building into a panic. Dora did a great job staying calm as the fire alarm was going off. Note: This video contains flashing lights. If you have epilepsy, do not watch this video, because people with epilepsy get seizures from seeing flashing lights or patterns.
