The feisty reptile was being lifted into a vehicle when it headbutted an animal catcher in a last-ditch attempt for freedom.
An alligator made a last-ditch attempt for freedom by headbutting a captor in Florida, knocking him out cold.
The feisty gator, which was tied up at the time, was being lifted into the back of a vehicle to be driven away.
It took three men to hoist the 2m (8ft) animal into the back of the pick-up truck.
As the reptile was almost securely stowed away, it suddenly lashed out.
It headbutted one of the animal catchers and knocked him out cold – sending his sunglasses flying off his head in the process.
The alligator was eventually taken away.
Neighbours say the alligator was walking through front yards before trappers arrived.
The condition of the man who was knocked out by the alligator is unknown.
