The thief was on his way out of a jewellery shop in Mauléon-Licharre, in the Pyrénées-Atlantiques, when he apparently just couldn't get his hips back through the hole he'd made in the window.
Police who arrived at the scene had the last laugh, sharing a picture of the man (with his face blurred out) on their social media feeds with the viral hashtag #Thuglife.
Fire fighters were called in to enlarge the hole in the window so they could pull the man through.
The police later took to Facebook to share another photo of the man (see below), this time from another angle, adding a lengthy caption about the night's proceedings.
They said that officers had earlier been called out to the scene, but had found nothing suspicious. It was during a second call out to the area that they found the bungling burglar.
They added that they suspected the man had made multiple trips to the jewellery store, judging by the stolen goods they found at his home.
The burglar spent the night in prison and will face court on Monday.
