Man pops question with penguin at Pittsburgh Zoo

When Mitch decided he wanted to propose to Casey, he knew it had to involve penguins.

In a YouTube video from shofilmspgh, Mitch said on their first Halloween together, he went out and got matching costumes they could wear - full penguin outfits. From there, the theme continued through their relationship.

"She's a very special girl, and I'm very grateful to have her in my life," Mitch said.

He knew he wanted to propose using a penguin, he even considered buying one. Then Mitch contacted the Pittsburgh Zoo, asking if they could help him propose to Casey. They devised a scheme - sending a letter to Casey typed on zoo letterhead saying she'd won a contest for a behind-the-scenes penguin experience.

This is what happened when they got there:

"You've really changed my life. I've changed inside and out. And I cannot wait to start a family with you, grow old with you, and do everything with you," Mitch said in the proposal.

In the end, Casey said yes, and Mitch took her on a helicopter tour.

"Mitch did it perfectly," Casey said. "I always tell him, I say, don't buy me things, let's do things. So when I saw the helicopter, that was hysterical to me because I was like, he was paying attention!"

On the YouTube page, the couple thanks the zoo, its staff, the helicopter company, and more, including Mickey the penguin, who carried the ring.
