A Boxing Day bottle of brandy led a Carlton man to take off his shirt in a Worksop pub, then punch a bouncer.
Karl Deakin, 32, said he downed the bottle of booze on 26th December before heading into town and drinking several whiskies.
He ended up in the CornerHouse pub on Bridge Place, where things turned sour, Worksop magistrates heard.
Prosecuting, Ruth Snodin said a member of door staff had approached a topless Deakin, and asked him to dress himself - which he did.
Moments later the he was confronted by Deakin and several others. When directed towards the door, Deakin punched the bouncer’s jaw.
He was then wrestled to the ground and restrained by security staff.
In police interview Deakin said he could not remember anything about the assault because he was too drunk.
He told police that a neighbour had given him a bottle of brandy for Christmas, which he had drunk during the day before going into town.
Defending, David Verity said Deakin apologised after seeing CCTV of the punch. He admitted common assault.
“Mr Deakin has struggled with a drink problem for quite some time and has made strenuous attempts to resolve that,” he said.
“He says in the weeks before Chirstmas he had not had a drink, hence the behaviour after a bottle of brandy.”
Deakin, of Lime Tree Avenue, was bailed until sentencing on 30th January. He must not enter any Worksop town centre pub. Magistrates refused to rule out a jail term.
