Nick Bonino was rocked to his very core Monday. He'll never look at half of his teammates the same again. His worldview changed forever.

Tweet from @NickBonino: Apparently guys on team button dress shirts top to bottom...that is bananas! Never seen before. Only normal way is bottom to top, thoughts?

The Pittsburgh Penguins forward was shocked to discover that some people prefer to button their shirts from top to bottom, instead of his favored method of bottom to top.

Bonino then polled the room and verified the stunning results.

Tweet from @NickBonino: I'm learning its pretty much a 49/49 split, with 2% goalies who alternate down then up. And each side has no idea the other exists #buttonup

Dissatisfied with the small sample size of the Penguins locker room, Bonino took his quest for validation to his 57,000-plus Twitter followers and got more than 16,000 votes, while deflecting critics who argued that they're called "button-downs" for a reason. For the record, a button-down has buttons on the collar and does not refer to the direction one buttons the shirt.

Unfortunately, he didn't get the affirmation he was looking for because 61 percent sided with top to bottom.

Tweet from @NickBonino: I guess this should settle it. Do you button your dress shirt from bottom to top like a normal person, or top to bottom.

You think you know people. What a world.
