A 20st man crushed a pub-goer's ribs when he sat on him during an argument in a beer garden.
Overweight Michael Eldin, 47, was told by a judge he had used his weight as a "weapon" to pin his victim to the ground.
Unemployed Eldin, who walks with a stick, had a drunken argument with Daniel Watson about his son.
The father-of-two grabbed Mr Watson by the throat and pinned him against some wooden patio railings in a pub beer garden, repeatedly banging his victim's head.
When Mr Watson fell to the ground, Eldin knelt on his 12st victim, breaking his ribs.
Prosecutor Jharna Jobes said: "All the evidence was on CCTV, it was very quick.
"He bashes his head against wooden railings five times and he kneels on his ribs. He is a large man and the complainant is very small."
The incident happened at The Plough Inn in Snaith.
Mr Watson suffered two broken ribs and a broken collarbone in the attack.
Mr Eldin's solicitor Ian Phillip said: "Both parties had been out drinking and the complainant accepts having more to drink.
"This is clearly out of character."
Eldin, of St Lawrence Avenue, Snaith, pleaded guilty to assault occasioning actual bodily harm on September 8 last year.
The court heard his partner is also not working and is in receipt of carer's allowance to care for Eldin.
Judge John Dowse told Eldin a 20st man would be "equal to a weapon".
He said: "You have committed a serious offence.
"I take into account you are not well and have a physical disability but, nevertheless, 20st of you came to rest on this complainant, causing him a fracture to his collarbone and ribs. You pleaded guilty and this was, in any event, out of character for you.
"This was violence in the street and as such must be punished by a prison sentence. However, in the circumstances of this case that sentence will be suspended."
Eldin was given a four-month prison sentence, suspended for 15 months.
Judge Dowse warned Eldin to stay out of trouble or face the consequences.
He said: "If you commit another offence punishable by imprisonment in the next 15 months, you will go to prison.
"If you stay out of trouble, you will hear nothing more about it. It would be nice to think we will never see you back in this court again.
"However, this man was injured and it seems appropriate to me that an amount of compensation be paid to him."
Eldin was also ordered to pay £200 compensation, which will be deducted from his state benefits over the next 12 months.
