Water fountain? Bidet? We’ve all gotten them mixed up before, right?

Like a lot of people over the weekend, you might’ve spent a ton of time binge-watching Season 2 of Netflix’s Stranger Things, starring Finn Wolfhard, who plays the character Mike Wheeler.

But fret not, because there are no spoilers about the new season in this post. There is, however, a very amusing story about an unfortunate “water fountain” incident Wolfhard recently recounted on his Twitter feed.

Moments later, the actor revealed that what he presumably thought was an object from which he could receive a refreshing drink of water was actually a bidet.

Soon after, Wolfhard tweeted another photo, this time featuring a description of what a bidet is and what it does.

Yep, it’s pretty much used for cleaning your butt. Quite the opposite of a water fountain.

BuzzFeed News has reached out to representatives of Wolfhard in order to get to the bottom of this pressing matter.
