Two teenagers who murdered a man at his home in south Wales were caught after boasting to friends, Cardiff Crown Court heard.
Richard Shanahan and Adam Smith, both 18, were jailed for life for a "prolific and ferocious" attack on Richard "****ie" Dyas.
They admitted murdering the ex-security guard, 47, who was found dead in bed at his home in Mountain Ash in March.
Imprints from Shanahan's trainers were visible on Mr Dyas' face and chest.
Mr Dyas choked on his own blood after the attack.
Shanahan and Smith, both of Mountain Ash, were given life sentences on Friday.
The court heard their 22-stone victim, who was described as "friendly, naive, kind and gentle", asked them to break into his home in Mountain Ash after it was repossessed by a building society.
Prosecutor Jeremy Jenkins said: "Shanahan popped the lock and he and Smith kicked down the door and they all went in.
"Mr Dyas gave them alcohol and electrical equipment to thank them for getting him back into his home - then the pair left."
But the pair returned in the early hours while an unsuspecting Mr Dyas was sleeping.
The court was told Smith has since shown remorse
Mr Jenkins said: "We can't say exactly what happened that night - only three people know and one of them is dead.
"But Shanahan and Smith punched, stabbed and stamped on their victim as well as whipping him with a fishing rod.
"The next day they boasted to friends about the attack and Shanahan said: "I stabbed him and kicked him and danced on his head."
Judge Mr Justice Lloyd Jones ordered Shanahan to serve a minimum of 18 years and Smith a minimum of 17 years.
The court was told Smith has since shown remorse by saying: "No one deserves what we did to him."
Mr Dyas suffered fractured facial bones and stab wounds to the chest and legs.
At sentencing the judge told the pair: "It was a prolific and ferocious attack by two fit young men on a man who couldn't defend himself.
"You inflicted considerable suffering before he died."
