Family Story

My mom always tells the story about how her brother lit a mattress on fire. It goes like this:
The ice cream man was outside, and my uncle needed a nickel to get an ice cream. He was searching all over the house until he found one under his bed. He wasn't sure where it was exactly, so he lit a match and went under the bed to get it. As he picked the nickel up, he noticed a strange smell. It was coming from the mattress that he had lit on fire with a match! So, he ran down the stairs and got a mug of water. He then ran back up the stairs and tried to put out the flame, repeating this until his older sister noticed. She followed my uncle upstairs and saw almost the whole mattress in flames. She called the fire department and they put out the flames, but, they needed a new mattress.
