Yes, it's a real thing. Pizza Hut Canada made 100 bottles of perfume featuring the scent pizza.
Here's the full story: Grip Limited, an advertising firm that works with Pizza Hut Canada, originally originally floated the tongue-in-cheek notion on the Pizza Hut Canada Facebook page back in August as part of a broader push to promote more engaging social media activity. The post asked fans to dream up names for an imaginary scent inspired by "the smell of a box of Pizza Hut pizza being opened." But the fan response to the idea was so enthusiastic that Grip and Pizza Hut decided to make the perfume a reality.
A month and a half later, to commemorate the fact that Pizza Hut Canada had gotten 100,000 fans, the chain's community managers announced that the first 100 people to message them would actually get a bottle of Pizza Hut perfume. And sure enough, the bottles were shipped to those 100 lucky fans at the beginning of December.
