"I had been thinking about it for a couple of weeks, what should I do, how should I do it," Perron told stlouisblues.com. "I was going store to store all morning."

David Perron's idea to dress up as linemate Ryan O'Reilly sent him to about 20 different stores around St. Louis on Monday before the team's annual Halloween party.

He had picked up a fake beard, a "Band of Horses" T-shirt that O'Reilly frequently wears and some tight jeans that were rolled up to reveal a pair of dress shoes with no laces or socks. He also picked up a guitar, a Conn Smythe miniature trophy from the Blues' locker room and a guzzler helmet filled with O'Reilly's favorite beer and the letters "MVP" across the front. The costume was completed with a long ponytail because former Blue Pat Maroon had revealed to the team last season that O'Reilly used to have one.

"I heard before the party that 'Perry' was dressing up as 'O'Ry,' so I knew that was going to be fun," said linemate Zach Sanford. "He was pretty spot on. The best part for me was the dress shoes without the laces and socks."

Perron arrived at the party to plenty of laughter - Alexander Steen was said to be crying from laughing so hard - but O'Reilly was nowhere to be found.

"Everybody was there, everybody was like 'Where's O'Reilly? Where is he?'" Sanford said. "And then he rolled in… as a piece of French toast."

Yes, French toast.

With "Perron" and "57" on the back.

"Last year I was just toast," O'Reilly said. "I wanted to put a (French) spin on it. I had a little scarf and a beret. I put 'Perron 57' on the back and that made me French toast."

Tweet from @DP_57: Best part is we both didn���t know about this haha! Lots of inside jokes in this #halloween 🎃 https://t.co/wbhxKeLdG4

"I saw him walk in and was like 'what the heck is he, a piece of bread?'" Perron recalled. "And then he turned around and I saw my name and number and I was laughing so hard. He dressed up as me, I dressed up as him. We just thought we'd get the other guy and we both ended up getting each other."

Can you believe that? Two players that have found undeniable chemistry on the ice - they each contributed four-point performances in Sunday's 5-4 overtime win against the Detroit Red Wings - are also on the exact same page off of it.

"I don't know what to say other than it was extremely funny," Perron said. "It turned out to be a great night. I'm glad the guys liked it."
