Housebroken

Frosty the snowman told his wife Krystal that he didn’t want a dog.
Krystal insisted. “We need him for security,” she said.
“Dogs are messy things,” said Frosty. “And they make snow yellow.”
Frosty lost. They got the dog.
“Stupid dog,” mumbled Frosty.
Frosty tried to housebreak the thing, but it kept falling asleep in front of the fireplace and melting all over the carpet.
“Your dog wet the carpet again,” said Krystal.
“My dog?”
Frosty sighed, held up one of the dog’s coal eyes, and pointed it at the wet spot.
“Look what you did!” shouted Frosty. “Bad doggy!”
