Fire officials in San Leon, Texas, say they showed up at a burning house, only to find some people trying to wave them away.
Assistant Fire Chief Scott Lyons says a man with a garden hose told them, "Man, we got it."
When firefighters got inside, they found out why.
Authorities say it was a grow house, with more than 100 pot plants.
The Galveston County Daily News reports deputies have a suspect in custody.
