Daft Derek Hardman had raided the home of John Spencer, 71, and wife Betty, 77 and was found napping on the couple's sofa in their Manchester flat.
The shocked couple woke the criminal and asked neighbours to help hold him until the authorities arrived. Hardman, 31, even tried to bite one of them!
Police soon arrived at the scene and found diazepam pills in his pocket.
Hardman admitted to burglary, assault and possessing diazepam at Bolton Crown Court.
The court heard that he was on licence from a seven-year prison sentence at the time, so jailed him for a further two years and eight months.
