David Hasselhoff was not allowed in the Wimbledon because he was 'stickin' drunk'.

Hasselhoff slurred at the security staff who refused to let him in because he had no ticket plus he was in no shape to have respect for the competition. Hasselhoff has a long history with alcoholism. He kept shouting in the security guards face: 'You should let me in. Do you know who I am? I'm the Hoff!'
