When Charlotte firefighters aren't saving lives, they're saving the day -- at least that was the case for a group of kids on the west side of town over the weekend.

After leaving a call Sunday afternoon, firefighters from Firehouse 18 spotted the children lugging pots full of water from their sink to fill a pool for a boy's birthday.

It was a sweltering day and the crew stepped in and filled the pool with their firehose.

"What was just a simple task for us turned into laughter, smiles, and a lifelong memory for the neighborhood kids as well as the men on Engine 18," the station wrote on Facebook. "Proud to serve the WESTSIDE!"

The kids were thrilled, and a whole lot cooler.
