Today we lit the fireplace for the first time this year. It was making strange popping and sizzling sounds that we couldn't figure out. Then all of a sudden, it made a big POP and a little smoke came out. This is NOT supposed to happen since we have a gas fireplace. Of course, Mom and Dad turned it off right away. Once it cooled down Dad took the front apart and found the culprit...a toy I had stuffed in the top vent ages ago. I was wondering where that thing was! Dad says we were lucky it didn't do any damage other than ruining my toy....oops!!
