Santa Claus makes it look so easy.

The fire department in Tucson, Arizona got a call on Friday afternoon when people heard someone yelling for help from inside a vacant house.

And it turned out a guy in his 30s had tried to get into the house by sliding down the chimney . . . and got stuck.

The firefighters were able to rescue him . . . and cops arrested him for trespassing, drug possession, and an outstanding warrant.
