Salesman and small boy joke for kids

"Is your mother home?" the salesman asked the small boy.

"Yeah, she's home," the boy said, scooting over to let him past.

The salesman rang the doorbell, got no response, knocked once, then again. Still no one came to the door. Turning to the boy, the fellow said, "I thought you said your mother was home!?"

The kid replied, "She is; but this isn't where I live."
