A man living at the home explained how things happened.
"He decided to back his car up, inside our garage here and push the pool table into the kitchen," said eyewitness Timothy Miller.
Miller admits he was angry, came out and started hitting the driver with a pool stick. That driver took off but was later caught by Montgomery County sheriff's deputies.
The injured teen was taken to Texas Children's Hospital by Life Flight.
No word if the driver will face any charges.
