Flashing His Gnashers

Track of the day - Love Song Number 3 - Bagshaw.

The dog wandered into the room and sat down in the doorway grinning.
He was definitely grinning, though 'flashing his gnashers' might be a better description.
"What's he grinning at?" asked Bob.
"I don't know but he lookth different thomehow. Do you think he'th in pain?" said Harry, Bob's father in law.
The old man got up from his chair in front of the television and left the room. They heard him banging about upstairs.
The dog continued to grin at them from the doorway.
A few minutes later the old man came back down the stairs.
"Bloody dog," he muttered as he dragged the grinning hound behind him out of the room and into the kitchen.
"Let go! Give them to me will you?" he shouted.
The dog yelped once and water could be heard splashing into the sink.
The older man resumed his position in the chair in front of the television as if nothing had happened. The dog crept into the room and lay down quietly at his feet.
He was no longer grinning.
Harry, it seems, had been soaking his false teeth in a glass at the side of the bed. The dog had knocked over the glass, picked up the false teeth and brought them downstairs.
"I had a hell of a job getting them back off him," Harry later admitted. "Wish they bloody fitted me that well."
