Now, it's important to point out that Sesselman is no online celebrity. With just 200 followers on Twitter, it seemed pretty ludicrous that his humble plea for a pup would gain any traction at all, let alone reach a million people.
But Sesselman's not one to cower at the odds, especially with such an adorable dog on the line.
"I decided to give it a shot," he said.
And then something totally crazy and completely implausible happened: It worked.
"I posted it that afternoon, and when I woke up the next day I had 222 retweets and was impressed. The entire day my friends and I who went and saw her yesterday were just watching the retweets go up and up and up," Sesselman said. "I woke up the next day and it had 149,000 retweets, which I couldn’t believe. It was unreal to me that 149,000 people retweeted it, and then it just spread so much faster after that. In four days I got one million retweets, making it the 10th most-retweeted tweet of all time."
Here's that tweet:
